Dead Mosquitoes and Live Lice, Part 2

Continued from “Dead Mosquitoes and Live Lice, Part 1

So what about the live lice? When I went into the US Public Health Service in 1957, it was to fulfill my draft obligation after student deferments. Recall that the Korean War was from 1950 to 1953. Also that during WW II, DDT dusting powder was widely used to kill lice, especially in conquered civilian populations, to prevent the spread of typhus. But by the Korean War some lice had sneer at DDT and so something else was needed. Enter Dr. Wayland J Hayes and yours truly. Dr Hayes arranged for prisoner volunteers at the Federal Correctional Institution in Tallahassee, FL to be recruited to test the toxicity of malathion formulated as a dusting powder substitute for DDT. Malathion is an organophosphorus compound unrelated to DDT and was thought to have similar effectiveness and human toxicity.

Dr Hayes was the lead researcher and I was the lackey who did the cholinesterase analyses, etc. in the prison. (I have always enjoyed watching the expressions on people’s faces when I say I was in prison once.) The prisoners were told the possible adverse effects of the program and were given “good time” (reduced sentences) for participation. (After this one prisoner opted out but was later found to be consuming his own brew made with a smuggled, homemade still. Was that less toxic?)

The results were published in the Bulletin of the World Health Organization, (1960, vol 22, page 503-514) and on review I was impressed by one observation: “Although one of us (J.G.S.) had received, without injury, a 30-hour application of 10% malathion powder in preparation for the study of volunteers, . . . .” My small contribution to the advancement of science. Well, in retrospect I have to say that it was safer than dodging bullets in the Vietnam War, which was waging at that time.

Human infestation with lice is uncommon in this country and typhus is really rare. We have a lot to be thankful for in this country in spite of the vicissitudes of politics and the stock market. But there are still enough problems with antibiotic resistance and the lack of proper hand hygiene, etc. Maybe our watchwords should be Thankfulness, Vigilance, and Diligence. “May the Force be with you!”

Can the holidays make you sick?

What makes us get sick more often during the holiday season?

Many theories have been postulated and studied over the years and many factors are blamed for being virus enablers. Closer proximity of hosts (us) within closed spaces makes transmission easier due to the shared air we breathe while indoors and the common surfaces we touch as people share confined areas. Further, foods are presented and ingested in areas with higher germ populations due to the foregoing.

Other theories suggest that inactivity and depression generally increases with the cold and gloomy weather and this coupled with decreased exposure to the sun may tend to inhibit our immune systems.

We suspect that all of these factors and more contribute to the seasonal spike in illnesses. But, there are some commons sense actions that can help reduce your chances of being the next holiday (infection) host. The most effective way to reduce your risks of seasonal sickness is to wash your hands often, especially after shaking hands, touching surfaces in common areas such as handrails and countertops and especially before eating.

In the spirit of holiday cheer (and microbial fear) check out these funny new flu and handwashing posters meant to remind with mirth and good cheer.

Healthy holidays to all.

Government Study Says You’re Washing Your Hands the Wrong Way

…Which Is Gross and You Should Fix It

Hey, did you wash your hands recently? Well, you probably did it wrong. CNN pointed out a recent government study found that 97 percent of the time, people fail to properly wash their hands—a problem that can lead to all sorts of unnecessary illnesses being spread.

According to the US Department of Agriculture, people are falling short of meeting the standards for acceptable handwashing set by the Centers for Disease Control and Prevention. The bar to make sure your hands are sufficiently clean requires you to wash and scrub with soap for at least 20 seconds.

The study looked at 363 people in six kitchen test facilities located in the Raleigh-Durham region of North Carolina and in the town of Smithfield, North Carolina. What it found was nearly every person working in the kitchens failed to reach the handwashing standard set by the CDC, which is probably not reassuring if you’re currently out to eat at a restaurant in Tar Heel State.

Moments when you should wash your hands

Certain events, actions or circumstances can make handwashing more important. For example, after being in public places, or handling often-touched objects like handrails and doorknobs, before preparing food, before eating and after using the rest-room. When possible it is best to avoid touching moist areas of your body such as eyes, nose and mouth unless you first wash your hands. Further, it is advisable to wash your hands after touching those areas. Germs most often travel by climbing aboard hands until they find a good opportunity to jump off into food we consume or directly into the portals of our bodies (mouth, nose and eyes etc.). Before helping these bugs find the greener pastures and making us sick send them down the drain.

Prevention always starts with good hand hygiene

Searching for the cause of an E Coli outbreak can send investigators in many different directions. This is a reminder that good hand hygiene practices and proper food preparation are of utmost importance. E Coli can be found in contaminated soil or water but it can also be spread through infected people. Germs that make us sick are everywhere and while we cannot always control where or how our food is grown we can control how we prepare it and make sure our hands are clean when doing so. Check out these links to the latest news on the Romain lettuce E Coli outbreak and the CDC which both reference person-to-person contact and the importance of hand washing.

A virus spreads in just 2 hours. Why the war on germs is in your hands.

Germs are everywhere. In optimal conditions a virus can divide every 20 minutes, spreading rapidly where they dwell. In fact, contamination of a single doorknob can lead to the spread of viruses throughout an office building or hotel in as little as two hours.

Researchers from the University of Arizona, Tucson, placed a tracer virus on commonly touched objects such as a doorknob or tabletop. At multiple time intervals (from two-to-eight hours) the researchers sampled a range of surfaces including light switches, bed rails, countertops, sink tap handles, and push buttons. And guess what? Nearly 60 percent of the surfaces were contaminated within two-to-four hours.

“If we placed a tracer virus on the push plate to an office building, it ended up on almost 50 percent of the high-touch surfaces of officer workers’ hands within four hours,” says study author and microbiologist Charles Gerba, PhD. “In the case of the hotel, we placed the virus on the nightstand in one room, and it was spread to the next four rooms by the maid during cleaning.” Also, the first item to become contaminated in the workplace was the coffee pot handle. Other contamination hot spots are phones, computers, and desktops.

Of course, our own bodies play host to around 100 trillion microbes that together weigh more than two pounds. They are present on our skin, in our guts, in the crooks of our elbows, and just about everywhere else. Your immune system protects against most microorganisms, but there are hundreds of thousands of different kinds of germs, and some of them are good at mutating into things your body doesn’t recognize. And they make you sick.

To get an idea of just how many microbes we carry—and which ones spread fastest—researchers are even testing our most intimate possessions: our cell phones. In a small study, University of Oregon scientists tested the index fingers and thumbs of 17 subjects, along with the touchscreens of their smartphones. As you might expect, they found an 82 percent overlap between the most common types of bacteria found on participants’ fingers and on their phones.

So your cell phone is covered with a personal bacterium cocktail? Clean it with a soft cloth dampened with water and wipe it down, or use a disposable wipe made specifically for cleaning electronic screens. Use a cotton swab to get the dirt and grime out of small nooks in the phone. The same goes for all of your other gadgets, too, including remote controls, headphones and ear buds, your computer keyboard, mouse, and tablet screen.

Yes, the war on germs is in your hands. Handwashing is the number one way to prevent the spread of germs and illness. Just make sure you’re doing it right. Friction (especially between the fingers) and duration—20 seconds with running water—are both important. And anything your hands touch are carriers. Learn all about handwashing here.

Here’s something else to think about: On average, an office desk has 400 times more bacteria than a toilet seat. It’s not surprising; the toilet is cleaned regularly. And remote controls, computer keyboards, phones, and iPods get touched way more than the toilet. Multiple coworkers and guest also share them—yet they are cleaned less often. You can find component-specific cleaning supplies at electronics stores. However, most disinfecting wipes are safe for electronics—just make sure to read the label before using them.

This one seems obvious, but how often do you walk around your home or office and wipe off doorknobs, cabinet handles, and light switches? You really should give them a once-over using disinfecting wipes—and don’t use the same wipe for more than a few places before grabbing a fresh one.

It’s easy to keep things clean. Soap and water. Bleach and water. Disinfecting wipes. Common sense. With these simple weapons, the battle against germs can be won. But the first step is you. Now go wash your hands!
