Africa Fighting Malaria claims to be fighting malaria

July 6, 2010

In response to earlier analysis here, that Africa Fighting Malaria (AFM) does not appear to do much to fight malaria, Richard Tren wrote a comment to a post at TropIKA.

Tren is unlikely to respond here; I gather he does not want to answer questions.

I will comment more completely later — I’m still not sure just what AFM does to fight malaria.  It’s humorous that he calls my question an “ad hominem” attack; I ask the questions because Tren has led the fight in the unholy smear campaign against Rachel Carson, against the U.S. Fish and Wildlife Service, against dozens of other scientists and science itself, against saving the bald eagle, against wise use of pesticides, against bed nets, against fighting malaria other than poisoning Africa. Most recently, as Tren mentions, he published a book that repeats much of the inaccurate claims and hoaxes he has relied on before.  But he’s concerned about attacks on him personally, and not the substance.

Why am I concerned at all?  The AFM-led assault on the World Health Organization, Rachel Carson, malaria fighters in public health, scientists and environmentalists  has come at an extremely high cost in human life. It is impossible to know how many people have died needlessly from malaria, yellow fever, leishmaniasis, dengue fever and other insect-borne diseases in the absence of medical care or prevention programs in lieu of DDT, but it must be millions — many of them could have been saved but for policy-makers’ beliefs that an increase in DDT could poison these people to health quickly and cheaply.  The campaign in favor of DDT has hampered serious efforts to fight malaria especially, such as Nothing But Nets and USAID’s support for prophylactic measures to beat the disease.

Does Tren answer the question well, what does AFM actually do to fight malaria?

Help me find some substance here in Tren’s letter (unedited by me in any way):

Paul,

It’s hard to know whether or not to respond to this. To say that we are ‘under fire’ because of the sniping and ad-hominem attacks from a blogger who has, for some or other reason, decided to take issue with my organization is an exaggeration to say the least. However even though your post has so far received zero comments I’d like to make a few things clear for the record.

AFM was founded in South Africa in 2000 and we opened an office in the United States in 2003. We maintain an office and a presence in South Africa as well as an office in the Washington DC. You say that we have focused most of our attention on one issue – the desirability of using DDT in mosquito control programs. Actually we focus on malaria control programs, not mosquito control programs; but to an extent you are correct. We have focused on this issue because DDT continues to play an important role in malaria control in many southern African programs (and in some other countries) and over the years other countries, such as Uganda have attempted to use DDT but have been harshly criticized and domestic and international groups forcing DDT spraying programs to close down. AFM defends DDT because of its outstanding record in saving lives and because it is under attack. The scare stories and smear campaigns against this insecticide are so pervasive and the misunderstanding about it so widespread that it is vital for some group or individual to provide a counterbalance, based on sound science.

AFM was a critical voice in securing an exemption for the use of DDT in the Stockholm Convention, and our research and advocacy work helped to usher in far-reaching reforms to US support for malaria control. We recently published a major book on DDT and its role in malaria control – The Excellent Powder – see http://www.excellentpowder.org. Additionally, we have responded to several recent publications that seek to limit the use of DDT (and interestingly other insecticides such as pyrethroids), with letters in Environmental Health Perspectives, British Journal of Urology International and working papers published on our own website. We have publicly exposed and criticized the way in which anti-insecticide advocacy groups, like Pesticide Action Network, have lobbied against indoor residual spraying programs that are funded and maintained by the President’s Malaria Initiative (PMI). All of these letters and papers can be accessed from our website – if any of your readers have any difficulty in accessing them, I’d be happy to forward them.

A word on our critical review of a paper published in British Journal of Urology International. Several researchers from the University of Pretoria published a paper in late 2009 claiming that DDT use in IRS would increase the chance that a boy would be born with a urogenital birth defect by around 33%. This paper was widely covered in the media and caused considerable problems for the malaria control programs in southern Africa. One scientist in particular even claimed on a public TV program that DDT was linked to the case of intersex South African athlete, Caster Semenya; this was further promoted in the print media causing great concern among people living in malaria areas. As we documented in our review, the research paper was very deeply flawed and the conclusions of the authors were premature to say the least. Although it required a considerable investment of time and effort, we respond with a formal review of both the paper and the outrageous claims made in the media for which there was no scientific evidence. Our letter to the journal, which was co-authored by some senior malaria scientists from South Africa, was published in the journal. Although the authors of the paper were given ample opportunity to respond to our criticisms, they declined – which is telling.

You make the point that we have focused on DDT – true, we have done so because there is a need for someone to respond to the never-ending claims of harm. Someone has to stand up and defend the malaria control programs that are using DDT and implementing effective malaria control measures – perhaps if some of the other advocacy groups or individuals stepped up and helped to defend IRS and the use of public health insecticides, we wouldn’t have to spend so much of our time and energy doing it.

In addition to defending the use of public health insecticides, we strongly advocate for investments in new insecticides and against regulations and policies that may hamper access to insecticides or investment in new insecticides. For instance in 2008/9 we coordinated a response to proposed EU regulation of insecticides that could limit access to insecticides. (The various documents that I describe are available on our website) As an example of our work in this regard, we recently held a successful policy briefing on Capitol Hill (in Washington, D.C.) involving stakeholders from advocacy groups, donor agencies and the private sector. Again details of this are available on our website.

Aside from our advocacy and defense of public health insecticides, we have been successful in exposing the ongoing use of sub-standard malaria medicines as well as fake medicines in Africa. Our research studies have been published in Malaria Journal, PLoS One, and other journals. In order to maintain this project and to get safe and effective malaria medicines out to communities we have raised funds for malaria treatments and have focused on increasing access in Uganda. Again, details are available on our website.

Lastly AFM is involved in a research and advocacy program to remove import tariffs and non-tariff barriers from malaria commodities. As malaria programs are scaled up, it is increasingly important to ensure that barriers to access are removed – import tariffs and non-tariff barriers can be significant and AFM is very excited to be involved in this important area of research and advocacy. See http://www.m-tap.org for more details.

So, I hope that this helps to answer the questions about what we do. We are a policy and research group, we have never pretended to be anything else and our track record stands for itself.

Paul, if you want to have a discussion about our work, I’d be happy to correspond with you and your colleagues on a basis of cordiality and respect. I would be delighted to debate our work on DDT, public health insecticides, drug quality and import tariffs and non-tariff barriers, but let’s leave the sniping bloggers and their misleading and biased comments out of this.

Malaria tough to beat: Canadian Press review of The Fever

July 5, 2010

At Canadian Press, Carl Hartman reviewed The Fever: How Malaria Has Ruled Humankind for 500,000 Years, a dramatic work of non-fiction about malaria and mosquitoes by Sonia Shah (Sarah Crichton Books/Farrar, Straus and Giroux 2010).  Hartman concluded:

Evidence of mosquito resistance to the drug has been recently reported.

Shah is skeptical of a surge of private charity that emphasizes the use of mosquito nets following the decline of government-led anti-malaria programs in the 1990s. Acknowledging the contributions of Bill Gates and former Presidents George W. Bush and Bill Clinton, she lists Veto the ‘Squito, a youth-led charity; Nothing but Nets, an anti-malarial basketball charity; and World Swim Against Malaria. She quotes The New York Times as decrying “hip ways to show you care.”

Her own comment: “Just because something is simple doesn’t necessarily mean that people will do it.”

“(T)he schools, roads, clinics, secure housing and good governance that enable regular prevention and prompt treatment must be built,” she concludes. “Otherwise the cycle of depression and resurgence will begin anew; malaria will win, as it always has.”

Anti-environmentalists, anti-scientists, and other conservatives won’t like the book:  It says we can’t beat malaria cheaply by just spreading a lot of poison on Africa and Africans.

Especially if you’re doing the noble thing and vacationing in the Gulf of Mexico in Alabama, or Mississippi, or Louisiana, you may want to read this.  If you’re vacationing in the Hamptons, Martha’s Vinyard, or Cannes, buy several copies to pass out at dinner with your friends.

Annals of DDT: Malawi ponders DDT use against malaria

June 21, 2010

Here’s a news story that Richard Tren and Donald North hope neither you nor anyone else will read.  It says that Malawi is pondering whether to use DDT for Indoor Residual Spraying (IRS) to fight malaria this season — and it lists several other nations that use DDT in exactly that way.

Why do the Chronically Obsessed With Rachel Carson (COWRC) like Tren and North hope you won’t see it?

It says DDT is being used broadly against malaria, in several nations on two continents.  That directly contradicts one of their favorite claims, that environmentalists (always unnamed) prevent the use of DDT anywhere.  It also shows clearly that DDT is not banned in Africa, another claim they like to blame on unnamed environmentalists and “left” do-gooders.

Facts of the malaria fight are that the consensus among serious malaria-warriors favors the integrated pest management schemes Rachel Carson wrote would be the savior of pesticides, in 1962 (in international circles, it’s called integrated vector management, “vectors” being the carriers of disease).  Quite to the contrary of Rachel Carson’s being the cause of needless deaths to malaria, her methods are saving lives.  The death toll from malaria is lower now than it was when DDT was used more broadly, and used outdoors.

Malawi going for DDT to fight malaria

Nyasa Times, June 20, 2010

Malawi is contemplating to start using DDT, an organochlorine pesticide, as a precaution in the fight against malaria in the country.

Chris Kang'ombe, Malawi Secretary for Health - Nyasa Times

Chris Kang'ombe, Malawi Secretary for Health - Nyasa Times

Principal Secretary in the Ministry of Health Chris Kang’ombe (pictured) said in Lilongwe during the launch of this year’s anti-malaria campaign themed, “Malungo zii (Kick out malaria)”.

“We know that our friends from Zambia and other countries are using it as an indoor residual spraying and it is working, so we are looking into it if we can do the same,” said Kang’ombe.

According to 2004-2009 statistical data provided by the UN, World Bank, WHO and UNAIDS, there were 4,204,468 reported malaria cases, 12,950 estimated malaria deaths and 7,132 reported malaria deaths in Malawi.

“We sent a team to Zambia to do a research on the use of DDT in fighting malaria and once the recommendations are made we will see what to do. We know that they are successful but we have to look at what effects DDT has on environment and agriculture taking into consideration that our economy is agro-based,” he said.

Some commentators and activists have raised concerns about DDT contaminating the environment if it is used in vector control. As with the other insecticides used in IRS, DDT causes minimal or zero contamination of the wider environment. Because DDT does not escape into the wider environment, it poses little or no threat to wildlife.

Results from the 2008 MIS demonstrated the dramatic progress Zambia is making in its fight to control malaria. Since 2006, malaria parasite prevalence in children has been reduced by 50%, and moderate to severe anemia has been reduced by more than 60%.

DDT is not only highly effective in malaria control, but it is also significantly cheaper than the other insecticides that are suitable for indoor residual spraying (IRS). It is easy to use and safe for both the residents of houses sprayed and the sprayers themselves.

More people than ever are sleeping under bed nets and two-thirds of all households are protected by at least one ITN or indoor residual spraying.

Use of DDT to fight malaria has been increasing since it was endorsed in 2006 by the World Health Organization and the President’s Malaria Initiative (PMI), a U.S. aid program launched by former President Bush.

USAID provides approximately $26 million per year to Malawi under PMI to purchase and distribute about 1,600,000 long life insecticide-treated bed nets, according to its Malawi office fact sheet.

“It is also used to purchase and distribute a national supply of over 6.6 million doses of life saving artemisinin-based combination therapy (ACT) drugs, implement an Indoor Residual Spraying (IRS) programme for 28,000 households and provide preventive treatment for malaria nationwide for pregnant women attending antenatal care,” reads part of the report.

PMI activities began in Malawi in 2007 and the U.S. government has committed a total of $107 million for addressing malaria over the five year period of 2007-2012.

“With six million cases of malaria per year in Malawi, the fight against malaria is far from over but through close collaborations between the governments of the United States and Malawi and other partners, we are making progress,” said Curt Reintsma, USAID Mission Director.

In 2009, data showed that use of ITNs by vulnerable children improved to 61% from 37% in 2005.

“We rededicate our partnership between Malawi and the United States to defeat this preventable and treatable killer,” said Reintsma.

Kang’ombe said the ministry has been implementing several malaria control strategies aimed at reducing the burden of malaria to a level of no public health significance in Malawi. These strategic areas which are coordinated by the NMCP includes; Malaria Case Management, Intermittent Preventive Treatment for pregnant women (IPTp) where women are routinely provided with at least 2 doses of SP during pregnancy.

“Integrated Vector Management is another major strategy that the ministry of health is implementing as one of the control measures for malaria in Malawi. This involves distribution of Insecticide Treated Mosquito nets and Indoor Residual Spraying. Operational Research, Monitoring and Evaluation and Information, Education and Communication/Advocacy are some of the cross cutting strategic areas that are also being implemented,” said Kang’ombe adding.

Some nations which are using DDT are: Ethiopia, South Africa, India, Mauritius, Myanmar, Yemen, Uganda, Mozambique and Swaziland, Zimbabwe, North Korea, Eritrea, Gambia, Namibia and Zambia.

DDT may have a variety of human health effects, including reduced fertility, genital birth defects, breast cancer, diabetes and damage to developing brains. Its metabolite, DDE and can block male hormones.

Measles vaccine: Britain bans anti-vaxxer Wakefield

May 25, 2010

Dr. Andrew Wakefield’s license to practice medicine in Britain was stripped away by British authorities earlier today, due to his “ethical lapses” in conducting research against measles vaccines.

Wakefield’s research claims, published in the distinguished medical journal Lancet in 1998, sparked a worldwide hysteria over the claimed link of Mumps-Measles-Rubella vaccine (MMR) to autism.  The journal earlier withdrew the article when the research was exposed as faulty and reaching erroneous conclusions.

Lancet retracted the paper earlier this year.

Effects of Wakefield’s errors ripple across the globe, as children pay the price with measles rates up worldwide, especially in Africa, and in North AmericaRob Breckenridge described the damage for the Calgary Herald:

However, Wakefield’s foul legacy is very much consequential. His latest comeuppance is hopefully a small step in undoing that legacy’s damage, but much damage has already been done.

Wakefield authored a now-discredited paper published in 1998 in The Lancet, which implied that the MMR (measles-mumps-rubella) vaccine was linked to autism.

Numerous studies have shown no such link exists, but Wakefield’s research had the predictable effect of scaring people away from the MMR vaccine. Vaccination rates plummeted in the U.K., and the number of measles cases soared.

In 2008 in the U.K., there were almost 1,400 cases of measles compared with 56 the year Wakefield’s paper was published. In 2006, a 13-year-old boy died from measles — the first time in 14 years such a death had been recorded.

On top of the multiple studies rejecting the MMRautism link, The Lancet issued a formal retraction of Wakefield’s paper in February, citing his unethical and irresponsible conduct.

Once a disease like measles becomes rare, we tend to drop our guard, either forgetting how serious it is or assuming it can never come back. As we’ve seen in the U.K. it can come back with a vengeance. Unfortunately, it’s not only the U.K. where we’re learning that lesson.

This month, Alberta Health Services confirmed five cases of measles in the Calgary area. Given our lack of recent experience with measles — there was only one case provincewide in 2009 — AHS offered a primer on the disease.

Measles is extremely contagious, meaning one need not have close contact with an infected person. There is no cure, but vaccination can prevent it. There are still pockets of the province where vaccination rates are low and measles cases there have been higher.

Southwestern Alberta is one of those regions. Not only has measles made a comeback there — a 2000 outbreak closed a Lethbridge-area private school — but cases of mumps and whooping cough have been documented over the past two years.

In B.C., 87 measles cases have been confirmed this year. It’s believed many stem from infected out-of-country visitors at the Vancouver Olympics.

All cases involve people who were either not vaccinated, or only partially vaccinated. Eight cases were associated with a single household, where no one had been vaccinated.

As Typhoid Mary denied she could be the cause of the deaths of the people she cooked for, and so continued cooking, Wakefield promises to keep up his campaign for measles.

Instapundit’s Glenn Reynolds poisoned by DDT

May 24, 2010

You can read about it here, at Instapundit.

Reynolds wants DDT back because dengue fever showed up at Key West.  News for Reynolds:  We see it in Texas all the time, but usually among poorer people with Hispanic heritage who live along the Rio Grande.  (Funny how these conservative nutballs all worry about people, so long as they’re white, and rich enough to travel to tropical vacation spots; where’s Reynolds to worry about the people who supply his fruits and vegetables?)

One solution:  Improve health care to cure humans with dengue, and then mosquitoes that spread it have no pool of infection to draw from — mosquito bites become just mosquito bites.

Other preventives:  Drain mosquito breeding areas (tires, flower pots, potholes, etc.) within 50 yards of human habitation.  Mosquitoes don’t fly far, and if they can’t breed where people are, they won’t travel to find human victims.

Stupid, destructive solutions:  Spray DDT.  DDT kills insects, bats and birds that prey on mosquitoes much more effectively than it kills mosquitoes, and mosquitoes evolve resistance faster, and rebreed faster. DDT is especially deadly against brown pelicans — maybe Reynolds figures we don’t need to worry about them any more, since they’re under assault from the oil slick that threatens to kill the estuaries of Louisiana.  Were he concerned about the birds, surely he’d have realized his error, right?

So, why did Glenn Reynolds get stupid about DDT?  Why is he promoting DDT, instead of promoting ways to fight dengue?

____________

But, then, Glenn Reynolds has been a fool for poisoning (anyone but himself) for a long time:

_____________

United Conservatives of Virginia swallow the DDT poison, too.  Don’t these people ever study history?

Measles ride again

May 23, 2010

Those people who warn against vaccinating kids?  They are laying low today.  They didn’t pick up the New York Times as they usually do on a Sunday — they don’t want to know.

You may want to know, however.

More than 1,100 deaths from measles have been reported among 64,000 known cases in Africa the last year, it said. Chad, Nigeria and Zimbabwe have had the largest outbreaks.

“There is a widespread resurgence of measles with these outbreaks in over 30 African countries, some of which are seeing very high case fatality ratios,” WHO expert Peter Strebel told a news briefing.

Some 8,000 migrant children in Bulgaria also had the highly-contagious disease during the period, he said.

Measles deaths among children under five years old fell to 118,000 in 2008 from 733,000 in 2000, according to the United Nations agency’s latest figures.

But the WHO warned that a lack of funding and political commitment could result in a return to more than 500,000 cases measles deaths per year by 2012, wiping out the gains to date.

Avoiding vaccinations for measles suddenly may not be a great idea.


Good news: Warming probably won’t expand malaria much

May 19, 2010

A paper in the May 20 edition of Nature reports that global warming probably won’t expand the range of malaria much.  That’s good news.

Here’s the press release from the University of Florida, touting the paper written by two University of Florida researchers, among others:

Scientists: Malaria control to overcome disease’s spread as climate warms

Filed under Environment, Health, Research on Wednesday, May 19, 2010.

GAINESVILLE, Fla. — Contrary to a widespread assumption, global warming is unlikely to expand the range of malaria because of malaria control, development and other factors that are at work to corral the disease.

So concludes a team of scientists including two University of Florida researchers in a paper set to appear May 20 in the journal Nature.

Scientists and public policy makers have been concerned that warming temperatures would create conditions that would either push malaria into new areas or make it worse in existing ones. But the team of six scientists, including David Smith and Andy Tatem, faculty members with UF’s biology and geography departments and both at UF’s Emerging Pathogens Institute, analyzed a historical contraction of the geographic range and general reduction in the intensity of malaria — a contraction that occurred over a century during which the globe warmed. They determined that if the future trends are like past ones, the contraction is likely to continue under the most likely warming scenarios.

“If we continue to fund malaria control, we can certainly be prepared to counteract the risk that warming could expand the global distribution of malaria,” Smith said.

The team, part of the Wellcome Trust’s multinational Malaria Atlas Project, noted that malaria control efforts over the past century have shrunk the prevalence of the disease from most of the world to a region including Sub-Saharan Africa, Southeast Asia and South America, with the bulk of fatalities confined to Africa. This has occurred despite a global temperature rise of about 1 degree Fahrenheit, on average, during the same period.

“The globe warmed over the past century, but the range of malaria contracted substantially,” Tatem said. “Warming isn’t the only factor that affects malaria.”

The reasons why malaria has shrunk are varied and in some countries mysterious, but they usually include mosquito control efforts, better access to health care, urbanization and economic development. The banned pesticide DDT was instrumental in ridding the disease from 24 countries in Southern Europe, the former Soviet Union and elsewhere in the world between 1955 and 1969, Smith said. Researchers debate how the U.S. defeated malaria, but the reduction of mosquito breeding grounds, improved housing and reduced emphasis on agriculture that comes with development — and the reduced risk of bites that accompanies urbanization – probably played a role, Smith said.

“There is no one tale that seems to determine the story globally,” Tatem said. “If we had to choose one thing, we would guess economic development, but that’s kind of a cop out” because the specific mechanisms may still remain unclear, and controlling malaria might also help to kick-start development.

In any case, current malaria control efforts such as insecticide-treated bed nets, modern low-cost diagnostic kits and new anti-malarial drugs, have proved remarkably effective, with more and more countries achieving control or outright elimination. Unless current control efforts were to suddenly stop, they are likely to counteract the spread of mosquitoes or other malaria-spreading effects from anticipated temperature increases, Smith said.

Simon Hay, an author of the Nature paper and one of the chief architects of the Malaria Atlas Project, noted that modern malaria control efforts “reduce transmission massively and counteract the much smaller effects of rising temperatures.”

“Malaria remains a huge public health problem, and the international community has an unprecedented opportunity to relieve this burden with existing interventions,” he said. “Any failure in meeting this challenge will be very difficult to attribute to climate change.”

Key to controlling malaria is the treatment of the disease in human victims.  Malaria parasites must spend part of their life cycle in humans; if medical care can cure humans, mosquitoes have no well of the disease to draw from, to spread it.

This paper says that global warming won’t spread the disease, so long as medical care and local health officials can keep effective treatments — a complete cure for human victims — coming quickly.

Wall Street Journal’s DDT-fueled war on science

May 12, 2010

I don’t subscribe to the Wall Street Journal — their discounts to educators are lousy.

So I missed this editorial when it ran on April 24, 2010 (page A12), “DDT and population control – malaria still kills one million every year.”

Nominally, that should be good news.  At the peak of DDT use in the early 1960s, malaria killed about 3 million people annually.  By the time we banned DDT use on cotton crops in the U.S., the death toll was still about 2 million people annually.  From the heyday of DDT, we’ve decreased malaria’s death toll, to less than half what it was.

Editorial writers at the Journal don’t let facts get in their way when they go off on a misdirected political jihad or crusade.  Gross error Number 1:  They mislead readers about the facts.

They are claiming that a million is too many (it is), but they claim that the total would be significantly less if only Americans would attack Africa with poison.  We have trouble enough with wars in Afghanistan and Iraq, it seems to me.  There is no indication that we could reduce malaria rates with a lot of extra poison.  Malaria is a parasite in human blood.  To defeat the disease we have to defeat the infections in humans.  Mosquitoes just spread the disease from one human to another.  DDT does not cure malaria in humans; it is one preventive device of limited effectiveness.

What are they on about?

The Journal’s editorial writers said:

Environmental activists this week marked the 40th anniversary of Earth Day, which happened to fall three days before World Malaria Day. Insofar as Earth Day politics have contributed to today’s malaria epidemic, the two events are related.

You could see this one coming.  The reactionaries at the editorial seek out opportunities to criticize environmentalists, whose cause they see as anti-business.   The Journal’s editorial page usually carries an op-ed piece by Hoover Institute maven Henry I. Miller about once a year (see here, for example), claiming we need DDT to fight West Nile virus.  We don’t, of course.  West Nile virus-carrying mosquitoes are best fought with other pesticides, when pesticides are used.  They need to be hit before adulthood, while they are still larva, in the water.  DDT is exactly wrong for such applications.  But Miller’s piece comes around almost every year, as soon as the first West Nile virus infections in humans are noted.

So, since they so soundly disregard science on that diatribe, why not here, too?  DDT offers a great target for Tea Baggers, Know-Nothings, and truth bashers.  Most of the history of DDT was written before the internet, so it’s easier to spread falsehoods without contradiction.

Disinformation.  Propaganda.  Shame on the Wall Street Journal.

Earth Day and World Malaria Day are related in this way:  Environmentalists warned us that doing the wrong stuff in the environment would make it harder to fight malaria, and they were right.  People who resist clean air and clean water legislation also resist legislation to stop poisoning our planet.  Those people rarely do anything to fight malaria, either.  Human comfort, human health, human survival, is not what they are concerned about.

Earth Day founder Gaylord Nelson, a U.S. Senator from Wisconsin, was a leading opponent of the insecticide DDT, which remains the cheapest and most effective way to combat malarial mosquitoes.

Gaylord Nelson, the father of Earth Day, was governor of Wisconsin when the University of Wisconsin did the first studies showing that songbirds and raptors in Wisconsin were being wiped out by DDT. We should expect him to be an opponent of indiscriminate use of the stuff.  His state was on the road to ruin, and long before the federal government acted against DDT, Wisconsin had laws and regulations to limit its use.  Wisconsin’s wild populations recovered a bit more quickly because Wisconsin had acted.

Gaylord Nelson at the Apostle Islands, Photograph by Frank Wallick, 1967.

Gaylord Nelson at the Apostle Islands, Photograph by Frank Wallick, 1967.

Nelson also knew that, in the U.S., malaria was conquered by 1939 (according to the Centers for Disease Control).  DDT came along in 1946, seven years later.  While DDT was used to control mosquitoes in the U.S., it was for no disease control reasons — that was why so many people opposed the rather pointless use of the stuff.  And I suspect Nelson was savvy enough to know that DDT has not been the cheapest means of controlling mosquitoes for several years.  One application of DDT in Africa costs about $12.00, for the professional who must apply it, and the testing to determine whether DDT will even work.  One application lasts about six months.  So, for a year’s protection, DDT costs about $24.00 per house, per year.

Bednets cost about $10.00, and last about five years.  That works out to $2.00 year.  For $24.00, you could provide a dozen different nets in a home, though most homes would use them only to protect children.

Moreover, recent test runs in Africa show DDT about 25% to 50% effective in reducing malaria incidence, while bednets are about 50% to 85% effective.  Nets are cheaper and more effective.

Doesn’t the Wall Street Journal have fact checkers?  Or do they just not care about the facts?

Rachel Carson’s 1962 book, “Silent Spring,” misleadingly linked pesticides to cancer and is generally credited with popularizing environmental awareness.

Wrong on three fronts.  Carson noted that the family of chemicals from which DDT comes might have links to cancer, but she did not make the claim that DDT is carcinogenic.  DDT was banned because it’s a long-term, deadly poison that destroys ecosystems.  Cancer in humans was not a part of the equation.

However, DDT is now known to be a weak human carcinogen.  Every cancer-fighting agency on Earth lists it as a “probable human carcinogen” (it is confirmed to cause cancer in other mammals).  Can’t the Wall Street Journal find the phone number of the American Cancer Society?

DDT earned its ban because of 20 years of research data by 1972, showing that DDT kills virtually everything it comes in contact with that is smaller than a large man, and it destroys ecosystems.  Talking about DDT’s carcinogenicity is a red herring.  Carson didn’t claim DDT was a significant cause of cancer, nor was DDT banned from agricultural use because anyone thought it was a significant cause of cancer.  Yes, DDT is a weak human carcinogen, contrary to the Journal’s implication; but no, that’s not why it was banned.

Carson’s book certainly ignited concerns about human activities affecting environment other than land development.  But “environmental awareness” is as old as our nation, at least.  A hundred years prior to Rachel Carson’s book, the U.S. set aside the world’s first National Park, Yellowstone.  60 years earlier, Teddy Roosevelt and Gifford Pinchot led the drive to conserve the nation’s forests.  The Soil Conservation Service, a New Deal program, worked to save soil on farms and unimproved areas, a good 30 years before Carson’s book.  Environmental awareness is an almost-congenital trait in Americans.  Rachel Carson sounded alarms about new reactive chemical combinations.  Americans were already alert to the need to save soil, water, air and wild spaces.

We banned DDT to save our crops and to save our wildlife.  Those are good reasons to keep the ban today.

But other leading greens of the period, including Nelson, biologist Paul Ehrlich and ecologist Garrett Hardin, were also animated by a belief that growth in human populations was harming the environment.

Nelson thought the U.S. needed to slow immigration (see more below).  Ehrlich feared a massive round of starvation, which was staved off only with the Green Revolution and billions of dollars of foreign aid money, the good luck of our having Norman Borlaug and the Rockefeller Foundation, and major economic change in nation’s like India and China.  Hardin pointed out that even the best intentioned people needed a structure to encourage them to conserve, else conservation would not take place.

They all recognized that while any human could minimize her impact on the natural world, no one person could ameliorate all the effects of billions of people.

“The same powerful forces which create the crisis of air pollution also are threatening our freshwater resources, our woods, our wildlife,” said Nelson. “These forces are the rapid increase in population, industrialization, urbanization and scientific technology.”

Notice, please, that Sen. Nelson did not suggest humans should do anything to cause or encourage massive human death (nor did the Journal do the courtesy of noting where they quoted him from).  He merely notes that air pollution and water pollution, and a lack of freshwater, are created by human populations, industry, urban sprawl and technology.  All of these things threaten human health.  Nelson is concerned that we not add to human illness and misery.  That’s not what the Journal’s editorial wants you to think, however.  It will suggest instead that Nelson urged more human suffering and death.

How craven must an editorial board be to accuse good people, falsely, of such sins?

In his book “The Population Bomb,” Mr. Ehrlich criticized DDT for being too effective in reducing death rates and thus contributing to “overpopulation.”

I doubt it.  I can’t find anything quite to that description in my copy of the book.  It’s a common internet legend (one level dumber than urban legend) — but shouldn’t the Wall Street Journal have higher standards than to use for documentation, “my cousin Clem heard a story about a person his aunt once knew?”

Hardin opposed spraying pesticides in the Third World because “every life saved this year in a poor country diminishes the quality of life for subsequent generations.”

Now the Journal is making things up.  In the essay from which the Journal quotes him, Hardin wrote about the dangers of uncontrolled immigration and population growth — almost sounding like an angry Arizona Tea Partier at times — but never did he get close to suggesting that we should not suppress malaria, for any reason.  (Wise readers may wish to see what Hardin actually said, where he really went awry if he did, and how his words resonate today, at his essay, “Living on a Lifeboat.”  Writers at the Journal should be ashamed of savaging the reputation of a guy who is so much in tune with what they usually write.  Notice Hardin does not mention DDT, use of pesticides in foreign nations, malaria, nor any other disease.  He rails at starvation, however.)  When the Wall Street Journal engages in fiction, shouldn’t they let us know?

For these activists, malaria was nature’s way of controlling population growth, and DDT got in the way.

Gee, in context, that’s all fiction. Never did Sen. Gaylord Nelson claim malaria was a good population control tactic, nor that we should stop using DDT to allow more people to die. Those are whole cloth lies. Never did Garrett Hardin say either of those things. Never did Paul Ehrlich say those things.

For anti-science activists, like the writers at the Wall Street Journal’s editorial page, falsehoods have become coin of the realm, and DDT is just one more sciency thing to try to use as whip against political opponents. The serious question is, why is the Wall Street Journal opposed to clean air and clean water?  Why are they trying to politicize things at all?

The writers at the Journal continue:

Today, malaria still claims about one million lives every year—mostly women and children in sub-Saharan Africa. There’s no evidence that spraying the chemical inside homes in the amounts needed to combat the disease harms humans, animals or the environment. Yet DDT remains severely underutilized in the fight against malaria because the intellectual descendants of Senator Nelson continue to hold sway at the World Health Organization and other United Nations agencies.

Full disclosure would be good here.  Malaria death rates are at the lowest point in history, at least since 1900.  Yes, too many die — but it’s not the fault of “not enough DDT.”  No nation that uses DDT has ever succeeded in eradicating malaria with pesticides alone.  Only those nations that assaulted malaria from the  human side, treating malaria in human victims, have been successful in eradicating the disease.  DDT use was essentially suspended in Africa by the World Health Organization in about 1965, because overuse of DDT in agriculture had bred mosquitoes that are resistant and immune to the stuff.  No amount of DDT spraying, anywhere, can reverse that.  Spraying DDT where mosquitoes are unaffected by it, is stupid.

Plus, studies indicate a correlation between DDT use, even in those small amounts, and premature deaths to children in the households sprayed.  DDT is not harmless.  DDT is not benign.

DDT has never been banned in Africa, and even under the 2001 Persistent Organic Pesticides Treaty (POPs) DDT has a special carve out to keep it available to fight malaria, despite its being a destroyer of worlds.  So implicit in the Journal’s screed here is that Africans are too stupid or lazy to use a substance that would save their children and themselves from malaria, though it’s available relatively cheaply.

Is DDT “underutilized?”  Again we should ask, why would anyone use DDT where it is not effective? Then we should ask, who would use DDT in fighting disease in Africa, and do they use it?  It turns out that DDT is not completely superfluous to all mosquito populations.  But testing is required to be sure DDT will work — were an organization to use ineffective pesticides, thousands could die, and the testing is therefore a preservation of human life.  And, because of past incidents in Africa, for example when DDT killed off the fish local populations depend on for their food, DDT use is extremely limited, to indoor applications only, and only by trained professionals who limit its spread.

WHO has been using DDT in Africa for indoor residual spraying (IRS) since the 1950s.  Use was slowed when DDT’s effectiveness was compromised.  In recent years WHO held a press conference on DDT to encourage locals who fear DDT poisoning to go along, and since 2005 DDT’s effectiveness appears to be dropping.  But DDT is available for use wherever it is needed to fight malaria in Africa.

Is the Wall Street Journal calling for mass poisoning of Africa?  What else could they be talking about?  Why would they call for such a thing?

The Journal claims WHO and other UN agencies are “under the sway” of Sen. Nelson, and that’s bad?  Let’s be clear:  Nelson didn’t oppose use of DDT in Africa to fight malaria.  UN’s WHO is the leading continent-wide advocate of proper use of DDT to fight malaria.  If the Journal claims that current, appropriate use of DDT is too little, what is the Journal advocating?

The good news is that the Obama Administration has continued the Bush policy of supporting DDT spraying in Zambia, Mozambique and other countries where the locals want it used. “Groups like the Pesticide Action Network have lobbied the U.S. Agency for International Development to stop spraying DDT, and Obama is ignoring them so far,” says Richard Tren of Africa Fighting Malaria, an advocacy group. “They’re prioritizing what makes sense from a science and public health point of view.”

Let’s be clear:  The Bush administration refused to allow U.S. money to be used to purchase DDT, or to use DDT, until about 2005.  Environmental Defense, the organization that first sued to stop DDT use in the U.S., argued for years that DDT should be allowed in the limited use WHO proposed, but Bush’s people stood firmly opposed, though never explaining why.  In any African nation where local people want DDT, it’s freely available with other money, of course.  So U.S. opposition, bizarre as it was, was not and is not a barrier to DDT use.

Most environmental groups favor beating malaria, and if a bit of DDT carefully controlled will help do the trick, so much the better.  While business lobbyists have falsely impugned environmentalists for years on this point, actual opposition to DDT use has come, in Uganda for example, from business groups.  Tobacco growers claim they fear some DDT will somehow get on tobacco leaves, and that will make the stuff unsaleable in the European Union.  Cotton growers fear any faint traces of DDT will ruin sales of organic cotton to the EU.  These business groups sued to stop DDT use against malaria in Uganda.

But environmental organizations, like ED, the Sierra Club, and others, have been fighting malaria for 40 years.

Which is more than we can say for Richard Tren.  Tren is one of two or three of the leading false propagandists for poisoning Africa in the world.  He tells false tales about Rachel Carson, false tales about DDT’s harms and effectiveness, and as best I can tell he has never lifted one finger or written one check to fight malaria himself, while taking tens of thousands of dollars to spread his false tales.

There are dozens of noble malaria fighters out there whose opinions we should seek — Socrates Litsios, the late Fred Soper, to mention two.  Why does the formerly august Wall Street Journal use Richard Tren as a source, when there are authoritative people handy to talk?

DDT helped to eradicate malaria in the U.S. and Europe after World War II, and the U.S. is right to take the lead in reforming public health insecticide policy and putting the lives of the world’s poor above green ideology.

Printed in The Wall Street Journal, page A12

According to the history of malaria at the CDC, malaria was essentially wiped out in the U.S. by 1939.  DDT was not available for use for another seven years.  Malaria was gone from northern Europe by World War II.  DDT was a tool in the final eradication of the disease in Italy and Greece.  But the main campaign against malaria was in curing the disease in humans, before the mosquito populations could rise up.

Among the nasty facts of science the Journal either does not know, or refuses to say, DDT can’t eradicate mosquitoes.  In anti-malaria campaigns, DDT is used to knock down the mosquito populations temporarily, so that the disease can be cured in humans.  Mosquito populations will quickly rise again, and in even greater numbers — but if there is no human reservoir of malaria parasites for mosquitoes to draw from, they cannot spread the disease.  Malaria parasites must spend part of their life cycle in humans, and part in mosquitoes.

Curing malaria in humans is the tough part.  It requires money to improve medical care, for accurate and speedy diagnoses, and for prompt and complete treatment of the disease in each patient.  Preventing malaria is aided greatly by better-built homes with screens on windows, the sort of stuff that requires people to have more than subsistence incomes.  So beating malaria generally requires economic development, too.

How much easier is it to bash environmentalists than to confront the real causes of malaria.  Bashing environmentalists won’t do anything to relieve human suffering nor eliminate the disease, so we can bash environmentalists again next World Malaria Day, and next Earth Day — all at no cost to us, safe in our Wall Street Journal offices in Manhattan, New York, U.S.A.  The Journal has fallen victim to bold purveyors of junk and voodoo science, and bogus and voodoo history.  Shame on the Journal.

Curing the disease in humans means the mosquitoes are mere nuisances, and no longer vectors of disease.  Killing the mosquitoes with poison means the disease will be back with a vengeance in a few weeks or months.  Curing humans is more difficult, and more costly — but it saves lives and can save Africa.  We cannot poison Africa to health.

It’s curious, though:  How did they get so poisoned by DDT, up in that office building?

Utah legislative craziness takes dark turn

March 1, 2010

Today I discussed legislative craziness, and she was surprised to discover Utah’s wackoes like Rep. Chris Buttars are national, and perhaps international stars of legislative dysfunction.  In my e-mail I get notes talking about a silly resolution from South Dakota’s legislature.

Then I stumbled into this:  “Utah bill criminalizes miscarriage.

From what I’ve read of the bill, I agree that’s what it would do.  It’s sitting on the Utah governor’s desk right now, deserving a veto, but probably headed into the Utah Code.

If it becomes law, women might be well advised to avoid any activity while in Utah, certainly not skiing or snowmobiling, nor hiking or river running, nor even jogging.  A woman who had a miscarriage within a week of skiing in Utah would be hard put to provide evidence exculpating her from a charge that her actions caused the miscarriage.  The contest of expert testifiers could be tremendously expensive.  Colorado, Wyoming, Idaho, California and other states offer all of those activities, but without the specter of a murder charge to women who miscarry later.

No, there’s no excuse for a woman who doesn’t know she’s pregnant.

Yes, I know the bill was designed to punish the bizarre behavior of some people who attempt to induce abortion by physical activity early in a pregnancy.  No, I don’t think this bill does that job well, either.

You legislative drafters, take a look at the bill.  The language is bizarre, it seems to me — it backs into a law by defining what is not covered.  I see some great ambiguities.  The bill excuses medical abuse of the fetus — failing to get medical care for the mother, for example, which leads to death of the fetus — but calls into question any action a woman might take in seeking an abortion from a medical practitioner.  It seems to me that the bill directly strives to outlaw all medical abortions, though one section says that seeking an abortion is not covered.

Debaters would have a field day with the enforceability problems of this bill.

Oy.  From Chris Buttars, the craziness disease has spread to the entire Utah legislature.

Is there a quarantine law in Utah, for people who carry dangerous infections?

Resources:

  • Best description and discussion I’ve seen on the bill, at the New York Times; it confronts head on the chief problem with this proposed law:  It criminalizes the activities of a desperate young woman who needs counseling and other help, but does not need to be jailed, nor deserve it:

Lynn M. Paltrow, the executive director of National Advocates for Pregnant Women, a nonprofit group based in New York, said the focus on the child obscured the bleak story of the teenager, who also deserves, she said, empathy from the world, and the law.

“Almost nobody is speaking for her,” Ms. Paltrow said. “Why would a young woman get to a point of such desperation that she would invite violence against herself? Anybody that desperate is not going to be deterred by this statute.”


Nathan Wolfe’s jungle search for viruses | Video on TED.com (Why it’s important to beat H1N1, now)

November 29, 2009

Here’s Nathan Wolfe explaining how viruses work, quickly and at a high enough level to be entertaining, and explaining why we need to worry about H1N1.

Vodpod videos no longer available.

more about “Nathan Wolfe’s jungle search for viru…“, posted with vodpod

Wolfe also explained a lot at the TED Blog:

Take us back a step or two: How did swine flu enter into the human population?

Swine flu has been known since at least the early part of the 20th century, since the 1930s. It was originally a virus of bird origin — all influenza viruses were originally bird viruses — and it probably spread to humans before it was in pigs.

Now, we still haven’t received definitive information on the underlying genetics of this particular virus. But initial reports suggest that it may be what’s known as a “mosaic virus,” which includes components of swine influenzas, bird influenzas and human influenzas. A cosmopolitan virus like that wouldn’t be unprecedented. (Editor’s Note: see Joe DeRisi’s 2006 TEDTalk for more on state-of-the-art virus detection.)

But in any case, this is a virus that appears to come from pigs, and pigs in close proximity spread the flu in much the same way that humans do — coughing, sneezing, and so on. The virus probably initially entered into human populations through people who work with livestock.

Is swine flu here to stay?

Whether this particular virus will sustain itself and become a permanent part of the human landscape is unclear, but that’s certainly what we’re watching for. As it is, the virus may just disappear because of the weather; summers aren’t good for flu viruses.

So this heat wave is working in our favor?

It might be. The virus has had a good start, from the flu perspective, considering that this is really the end of the season. But the unseasonably hot weather may bode poorly for this virus’ potential to establish itself definitively and cause a pandemic. Had this happened in September or October, it would be much more concerning.

Having said that, it’s not impossible that a virus like this might “go into hiding” — in the southern hemisphere or the tropics — and might come to light again next year. So there will be a lot of discussion about expanding the fall flu vaccine to try to control it next cycle.

Is it really possible for us to prevent future outbreaks like this?

Yes, I believe it is. We spend tons of money trying to predict complex phenomena like tsunamis, hurricanes, earthquakes. There’s no reason to believe that a pandemic is harder to predict than a tsunami. And we’d be foolish not to include forecasting and prevention as part of our overall portfolio to fight these pandemics.

No health insurance: Can you look this man in the eye and tell him you want to let him die?

November 29, 2009

Our National Conscience, Nicholas Kristof asked the question in his column a week ago:  Are we going to let John die?

45,000 Americans die each year because of a lack of health insurance.  What do you think:  Should we allow John to die?

Which system saves John’s life, “socialism,” or “free enterprise?”

Here, you can help:

UPDATE: Several readers have asked how they can help or if there is a fund to help John. There isn’t any such fund, but with John and Esther’s permission I’m posting their mailing address: John and Esther Brodniak, 770 W Main St., Sheridan, OR 97378.

H1N1 vaccine, a citizen’s duty

November 17, 2009

Claudia Meininger Gold practices pediatric medicine in Great Barrington, Vermont.  When someone recently suggested offering flu shots at polling places, it struck her that, like voting, getting a flu shot is a good citizen’s duty.  She wrote about it in the Boston Globe.

AS A pediatrician, I received my swine flu vaccine without a moment’s hesitation. I wanted to be available to treat the onslaught of illness, and to be able to go comfortably into a room with a coughing, miserable child knowing that I was not putting myself or my family at risk. I was astounded, therefore, to read recently, in a popular newsletter for pediatricians, a column by a pediatrician stating that he would not recommend the vaccine to his patients. His arguments were that the illness was relatively mild and the vaccine might not be safe.

In my practice, there are many parents who choose not to immunize their children. As a mother myself, I sometimes wonder if part of the motivation for this choice is to combat the helpless, scary part of loving someone so much. It can become overwhelming to contemplate everything that can possibly go wrong. Perhaps parents refuse vaccines because it is something they can control, a way in which they can “protect’’ their child. In the case of swine flu, or H1N1, this action is, in my opinion, misguided.

There are many different fears associated with vaccines, but the specific fear around H1N1 has its origin in a 1976 outbreak of Guillain-Barre syndrome, a disease that damages nerve cells, after mass vaccination against a swine flu. The website of the US Centers for Disease Control and Prevention addresses this issue:

“Several studies have been done to evaluate if other flu vaccines since 1976 were associated with GBS. Only one of the studies showed an association. That study suggested that one person out of 1 million vaccinated persons may be at risk of GBS associated with the vaccine.’’

The current method for making the H1N1 vaccine is the same as that for the seasonal flu vaccine. The only difference is that seasonal flu vaccine is prepared in anticipation of flu season, while manufacturing of this one was begun while the pandemic was in its initial stages. High-risk groups, such as the elderly and young children, receive the seasonal flu vaccine without a second thought.

It is true that for the majority of people H1N1 is a mild illness, generally causing two to four days of feeling lousy. But the virus is highly contagious. The sheer numbers are staggering. A school in Chicago closed last month when 800 of its 2,200 students were sick. With any flu there are people who will have complications and die. As the number of cases continues to climb, statistics are not in our favor.

For high-risk groups, such as pregnant women, talk of “mild illness’’ is meaningless. Stories are multiplying of the devastating losses of both baby and mother. In our small town there are young adults who were previously healthy now on respirators in intensive care units.

In a recent op-ed in The New York Times, Douglas Shenson proposed the use of polling places for vaccination. This led me to think of vaccination as a responsibility of being a citizen, analogous to voting. Just as one vote does not determine the outcome of an election, one person immunized does not halt the spread of illness. Yet voting is a civic duty. Similarly, vaccination, while benefiting the individual, serves to protect the population as a whole. Short of shutting down the country, mass immunization is the only way to stop the spread of this virus.

In addition, I feel that as a physician, it is my responsibility to uphold the recommendations of the CDC. If every individual citizen took it upon himself or herself to decide what was best for the country, there would be chaos.

Washing hands, covering our mouths when we cough, and staying home when we are sick are all ways to contribute to the common good. As responsible citizens, when the opportunity arises, and in keeping with CDC guidelines, we should all do our part and immunize ourselves and our children.

Nobody called for DDT to fight West Nile?

September 28, 2009

Was I too busy to notice?

With the exception of Glenn Beck’s idiot return to 1950s science in an effort to bring back 1950s politics, I didn’t see any major calls for DDT to be brought back to fight West Nile Virus this summer, not even from the Hoover Institute.

DDT is particularly ill-adapted for fighting West Nile Virus.  The mosquitoes that carry it are best fought in the larval stage, before they mature.  DDT is exactly wrong for water applications.

But that didn’t stop people from asking for DDT as a barrier to WNV in the past.  Is some intelligence taking hold now?

Did I miss the editorials?  Maybe it was a better summer than it felt like.

(Still fighting stupidity on bedbugs — taking longer than it should.)

Fighting the flu in Texas

September 27, 2009

Texas government worries about the flu, with good cause.

The Texas Department of State Health Services set up a flu information page at its website, urging Texans to act now to prevent trouble later:

Flu season is here — here’s what you can do:

  • Stay Informed
    TexasFlu.org is the DSHS site for flu information in Texas. Bookmark it. Sign up to receive Twitter and e-mail notices when information is posted.
  • Get a Seasonal Flu Shot Now
    Don’t wait. Get your seasonal flu vaccination now. It’s one of the best ways to protect yourself and others from seasonal flu. Also, be prepared to get the 2009 H1N1 flu vaccine later. It is expected to be available in mid-October.
  • Stop the Spread
    Wash hands frequently. Cover coughs and sneezes. Stay home if you’re sick. Have a plan to care for sick family members at home
  • 18 Texas kids have died from influenza in the past 52 weeks.  Health officials hope immunization will keep pediatric and other deaths low, for both the regular seasonal flu viruses and the novel H1N1 which is the subject of a WHO-declared pandemic.

    (By the way, “pandemic” does not have “panic” at its root; it’s a combination of “pan” from Greek and roughly meaning “all people“, and “demic” meaning a health issue “people. (See Mr. B’s comment below.)

    According to the World Health Organization (WHO), a pandemic can start when three conditions have been met:[1]

    • emergence of a disease new to a population;
    • agents infect humans, causing serious illness; and
    • agents spread easily and sustainably among humans.

    A disease or condition is not a pandemic merely because it is widespread or kills many people; it must also be infectious. For instance, cancer is responsible for many deaths but is not considered a pandemic because the disease is not infectious or contagious.

    Complaints that deaths are low from H1N1 should be regarded as a compliment to the work of health care workers and officials; and statements that we don’t have a flu pandemic ‘because not many people have died’ miss the definition of “pandemic.”)
