Annals of DDT: When they sprayed DDT from airplanes to stop polio

August 10, 2018

March of Dimes Foundation photo: “Nurses tended to polio patients in iron lung respirators at the Robert B. Green Memorial Hospital polio ward in San Antonio in 1950. It was a common scene throughout the polio crisis that swept Texas.” From the San Antonio Express-News article on the history of polio in the city.

It didn’t work.

In a desperate move to stop polio epidemics, after World War II but before the Salk polio vaccine was available, some American towns authorized aerial spraying of DDT over their cities.

Of course, DDT doesn’t stop viruses, and polio is a virus. Polio virus is not spread by a vector, an insect or other creature which might have been stopped by DDT, as mosquitoes spread malaria parasites and West Nile virus.

Aerial spraying of DDT against polio did not one thing.

A podcast from the Science History Institute discussed these misdirected events recently, and someone there did a sharp, short video to explain the issue.

YouTube explanation:

An animation drawn from episode 207 of Distillations podcast, DDT: The Britney Spears of Chemicals.

The podcast is a short 15 minutes, and fun, “Distillations.”

Americans have had a long, complicated relationship with the pesticide DDT, or dichloro-diphenyl-trichloroethane, if you want to get fancy. First we loved it, then we hated it, then we realized it might not be as bad as we thought. But we’ll never restore it to its former glory. And couldn’t you say the same about America’s once-favorite pop star?

We had a hunch that the usual narrative about DDT’s rise and fall left a few things out, so we talked to historian and CHF fellow Elena Conis. She has been discovering little-known pieces of this story one dusty letter at a time.

But first our associate producer Rigoberto Hernandez checks out some of CHF’s own DDT cans—that’s right, we have a DDT collection—and talks to the retired exterminator who donated them.

I bring it up here because in recent weeks there’s been a little surge on Twitter, and probably on Facebook and other places, in people claiming DDT causes polio, or causes symptoms so close to polio that physicians could never tell the difference. A lot of anti-vaccine advocates pile on, claiming that this would prove that the polio vaccine doesn’t work.

That’s all quite hooey-licious, off course. Polio’s paralysis of muscles in almost no way resembles acute DDT poisoning, which causes muscle misfiring instead of paralysis. As with almost every other disease, acute DDT poisoning can cause nausea; but DDT poisoning either kills its victim rather quickly, or goes away after a couple of weeks.

Polio doesn’t do that.

In the podcast, you’ll hear the common story of kids running behind DDT fogging trucks, because people thought DDT was harmless. In the concentrations in the DDT fogs, it would be almost impossible to ingest the 4 ounces or so of DDT required to get acute poisoning.

In any case, it’s one more odd facet of a long story of human relations to DDT and diseases. It’s worth a listen for history’s sake. But in this case, it’s entertaining, too. You’ll hear stories of people who opposed government actions to spray DDT, and who thought the government was too lax in its regulation and use of DDT.

National Infant Immunization Week, April 20-27, 2013

April 23, 2013

National Infant Immunization Week:  Find out about the power to protect with immunizations on http://www.vaccines.gov/

This week is National Infant Immunization Week designated by the U.S. Centers for Disease Control (CDC).  Vaccinations worked miracles in extending human lifespans, and in making childhood much safer from disease, for those children who get vaccinated.

Information following comes directly from the CDC:

Protect Your Baby with Immunization

Photo: A mother and childImmunization is one of the best ways parents can protect their infants from 14 serious childhood diseases before age two. Check to see if your baby is up to date on immunizations.

It is important for children to be fully immunized. Diseases that can be prevented with vaccines can be very serious – even deadly – especially for infants and young children. For example, children younger than 2 years old are at the highest risk for serious pneumococcal disease like pneumonia, blood infection (sepsis), and meningitis. Before the pneumococcal vaccine was used routinely, an estimated 17,000 cases of severe types of pneumococcal infection, like meningitis, occurred each year.

Immunization. Power to Protect.

Immunizations have helped to greatly improve the health of children in the United States. Most parents today have never seen first-hand the devastating consequences that vaccine-preventable diseases have on a family or community. While most of these diseases are not common in the United States, they persist around the world. It is important that we continue to protect our children with vaccines because outbreaks of vaccine-preventable diseases can and do occasionally occur in this country.

For example, in 2010, there were 27,550 people reported to have “whooping cough” (pertussis) in the United States. Twenty-seven deaths were reported – 25 of these were in children younger than 1 year old. In 2011, 222 people were reported to have measles in the United States – that’s more than any year since 1996. Measles is brought into the United States by unvaccinated U.S. residents and foreign visitors who get infected when they are in other countries. Measles is still common in many parts of the world, including Europe, Asia, the Pacific, and Africa. In fact, in France alone, more than 15,000 people were reported to have measles in 2011. Measles spreads easily, and it can be serious, causing hospitalization and even death. Young children are at highest risk for serious complications from measles.

Vaccinating your baby according to the recommended immunization schedule gives him or her the best protection against 14 serious childhood illnesses – like measles and whooping cough – before he is two years old. The recommended schedule is designed to protect infants and children early in life, when they are most vulnerable and before they are exposed to potentially life-threatening diseases.

Vaccine Information for ParentsVisit CDC’s vaccine website for parents.

The Diseases Vaccines Prevent

The recommended immunization schedule for babies includes vaccination protection against all of the following diseases:

Vaccinate On Time, Every Time

Even though the United States experiences outbreaks of some vaccine-preventable diseases, the spread of disease usually slows or stops because of immunization. If we stopped vaccinating, even the few cases we have in this country could very quickly become tens or hundreds of thousands of cases. Fortunately, most parents choose to vaccinate their children and immunization rates in this country are at or near record high levels. In fact, less than 1% of children do not receive any vaccines. However, some children have not received all of their vaccines and therefore are not fully immunized. It’s important that children receive all doses of the vaccines according to the recommended immunization schedule. Not receiving all doses of a vaccine leaves a child vulnerable to catching serious diseases.

That’s why it’s important to make sure that your child is up to date on his or her immunizations. Call your pediatrician to find out if your child is due for any vaccinations. Or, you can use this online tool to enter your child’s current record and quickly see if any doses have been skipped or missed. It is important to your child’s health to be up to date on immunizations.

Paying for Immunization

Photo: A babyMost health insurance plans cover the cost of vaccinations, but you should check with your insurance provider before going to the doctor. If you don’t have health insurance, or if your insurance does not cover vaccinations, the Vaccines for Children (VFC) program may be able to help with the cost.

The VFC program helps families of eligible children who might not otherwise have access to immunization. The program provides vaccinations at no cost. Children younger than 19 years of age are eligible for VFC vaccines if they are:

  • Medicaid-eligible
  • Uninsured
  • American Indian or Alaska Native,
  • Underinsured and vaccinated in Federally Qualified Health Centers or Rural Health Clinics.

Parents of uninsured or underinsured children who receive vaccines at no cost through the VFC Program should check with their health care providers about possible administration fees that might apply. These fees help providers cover the costs of giving the vaccines, including storing the vaccines and paying staff members to give vaccines to patients. However, VFC vaccines cannot be denied to an eligible child if a family can’t afford the fee.

Have Questions about Immunization?

  • Talk with your child’s health care professional, contact your local or state health department, or call the CDC at 800-CDC-INFO (800-232-4636).
  • Visit CDC’s vaccine website for parents

Whooping cough epidemic in Wenatchee, Washington, makes case for vaccinations

Professor Matthew Hay, the famous Scottish physician and public health champion, ” … assailed by the furies of typhoid, measles, influenza, whooping cough and scarlet fever,” the same furies that affect public health around the world, including Wenatchee, Washington  (Photo credit: Wikipedia)

Thinking about skipping the DPT shot for your kids?

Read this story out of the Wenatchee (Washington) World about what happens to a small town when a significant number of people do that, and one of the kids gets sick.

EAST WENATCHEE — With 31 cases of whooping cough reported in Chelan and Douglas counties, health officials are saying the disease has reached epidemic proportions.

“People should be taking action to prevent it from getting worse by getting their Tdap shots, especially those people who are around infants,” said Mary Small, director of community health and preparedness at the Chelan-Douglas Health District. “Infants are at highest risk for death and hospitalization.”

The shots are for tetanus, diphtheria and pertussis, which is also known as whooping cough.

At last report, in early May, the two counties had a total of 22 cases this year. In 2009, there were no cases of pertussis in the two counties; in 2010, there was one case; and in 2011, there were two cases and one probable case, Small said.

You say your town isn’t as isolated as Wenatchee, Alaska?  Then there are higher odds that some stray person with whooping cough will wander into your town.  Your town is not as small as Wenatchee?  Then the odds are higher that you’ve got enough uninoculated kids to make an epidemic spread quickly.

Vaccinate the kids, will you?  They don’t need whooping cough.

Is the anti-vaccine movement dangerous?

“DEADLY CHOICES”: PAUL OFFIT EXPOSES THE ANTI-VACCINE MOVEMENT.

There was never a time before people knew that falling trees and large animals with teeth can kill.  Microbes are another matter. They had been killing us for perhaps 200,000 years before Antonie van Leeuwenhoek showed them to us. Paul Offit and two colleagues worked for 25 years to develop a vaccine for the rotavirus, a cause of gastroenteritis that kills as many as 600,000 children a year worldwide, mostly in underdeveloped countries.  The vaccine is credited with saving hundreds of lives a day.  Offit wrote “Autism’s False Prophets” in 2008 exposing British physician Andrew Wakefield for falsely claiming the MMR vaccineis linked to autism.

Vaccination prevents more suffering than any other branch of medicine, but is still opposed by the scientifically ignorant who accept the upside-down logic of the alternative medicine movement.  Because vaccination of schoolchildren against virulent childhood infections is ubiquitous, crackpots, scoundrels and gullible reporters get away with linking it to unrelated health problems as they did in the 1980s with the ubiquitous power lines.  We still hear echoes of the power-line scare in the cell phone/cancer panic. Paul Offit has just written “Deadly Choices: How The Anti-Vaccine Movement Threatens Us All.”  We need to do everything we can to stop it.
