Does it create mutant strains of alcoholic germs?
Might my retirement savings have actually increased had I invested in the makers of Purell last year? In fact, alcohol-based hand sanitizers are tremendously effective in preventing the spread of the seasonal flu, H1N1, colds and other viral- and bacterial-based diseases; and sales are through the roof. There are in fact few negative consequences about this hand-sanitizer mania sweeping the country, although the gels do have their limitations.
Most respectable public health experts will tell you that hand washing with ordinary soap and water is the most effective way to remove germs from your hands. But "effective" is a questionable term.

The recommendation calls for hand washing with soap and warm water for at least 20 seconds to create a full lather and to reach all crevices of your hands and wrists, as advocated on Sesame Street yet rarely put into practice. Alcohol-based hand sanitizers kill most types of bacteria, viruses and fungi in a few seconds.

While rubbing your hands with sanitizer for 15 seconds is ideal, poor hand-sanitizer use still beats poor hand washing. And people seem to use hand sanitizers often — so much so that, from a public health standpoint, although proper hand washing is technically superior than alcohol gels most of the time, hand-sanitizer mania will likely be a more effective means to reduce disease transmission. Studies have shown how hand sanitizers reduce gastrointestinal illnesses in households and curb absentee rates in schools and workplaces.
Alas, you can't rely solely on alcohol-based hand sanitizers. Alcohol can kill bacteria but not necessarily clean your hands. If the items you are washing are likely to cause illness high risk , they should be washed at 60C with a bleach-based product. Items are likely to cause illness if you have someone in your home who has an infectious illness.
Should You Change Clothes When You Get Home to Get Rid of Germs?
The following items are also high risk:. Always remove any vomit or poo from clothing before washing and flush it down the toilet. Heavily soiled items and items used in food preparation should be washed separately from other items. You can protect yourself from infection by wearing gloves when handling high-risk laundry and always washing your hands thoroughly afterwards. If you are washing lightly soiled everyday items that are not likely to cause illness, a normal wash with a detergent will be very effective at reducing the risk of transmitting any infection.

Scientists have shown that the fist bump is more hygienic that is, it transfers fewer bacteria than the handshake, presumably because it exposes a smaller skin surface area.
That doesn't mean you need to start pounding it with subway handrails, however. Any difference in infectious disease risk is negligible at best—and certainly not worth the risk of wiping out in the car.

This will in fact allow you to avoid physical contact with the germs on the toilet seat. But no matter what you do, the contents of the toilet bowl will become aerosolized when you flush. Putting the lid down when you flush can help a bit here.
Again, this just keeps germs on the bottom of your shoes and off your hands. It's totally fine to flush with a hand as long as you wash your hands afterward—which you should be doing anyway. Alcohol-based hand sanitizers are just about as effective against germs as soap and water.

In general, you shouldn't worry about using Purell immediately after exposure to pathogens. As long as you don't touch your eyes, mouth, or any other mucosal surface, you should have plenty of time to wash away the germs—anywhere from five minutes to five hours for bacteria. Research into the biology of the built environment is evolving and could have wide-reaching impacts on future building design. The bottom line is that you shouldn't live in fear of high-traffic surfaces.

A ccording to Blaser, this type of contact simply isn't the way people get sick. There is no evidence that subway handholds and toilet seats are significant transmitters of disease. There is no evidence that people who commute by public transportation are more likely to get sick than people who drive.
