Flu Protection: Hand Sanitizer not Antibacterial Soap!

Flu Protection: Hand Sanitizer not Antibacterial Soap!

It's amazing how confusing it can be when a new disease emerges, and advice starts flying around. One thing that I want to nip in the bud right now is the idea that "antibacterial" soaps can be helpful for fighting Swine Flu. Wrong!

Hand sanitizers, which are usually alcohol-based, and are designed for use when you're not near a sink, are beneficial against the flu. Antibacterial soaps are useless and could be dangerous. Here's why:

First, influenza is a virus, so antibacterial products are useless. That goes for antibacterial soaps and for oral antibiotics as well;

Second, the soaps that are sold as "antibacterial" have been tested and found to be no more effective than regular soap and water;

Third, some research suggests that these antibacterial soaps may actually create antibiotic resistance in bacteria; an article from the journal of Clinical Infectious Diseases that summarizes this issue is here: pdf.

Finally, the ingredients in antibacterial soaps - triclosan or triclocarban - have some serious toxicity concerns. These chemicals pollute rivers and streams, are toxic to wildlife, can enter and accumulate in people's bodies, and disrupt hormone systems (triclosan interferes with thyroid hormone, whereas triclocarban has a testosterone-like effect). Stay tuned for more on this soon.

The bottom line is:

Don't use antibacterial soaps!  Do wash your hands frequently with regular soap and water, and do use hand sanitizers when you're not near a sink! Stay well!

One important thing to remember is that alcohol based hand sanitizer is not safe for little children. The high levels of alcohol can be absorbed into their skin, never mind the fact that their hands are always in their mouths. A tablespoon amount is toxic to small children! One should take the time and effort to wash your hands and your children's with soap and water! Please read this true article http://www.snopes.com/medical/toxins/sanitizer.asp

PLEASE PLEASE PLEASE - JUST WASH YOUR HANDS. DO NOT FUSS ABOUT ANTIBACTERIAL THIS, ANTIVIRAL THAT, JUST WASH YOUR HANDS. If and when people stop washing because they are told it will do little or no good, and trust me they will stop washing when they read this, we're looking at elevated rates of transmission and the spread of viruses, bacteria, AND misinformation. These posts often do more harm than good. For instance, I've already seen this blog posted on Facebook and the like - do you think the handwashing message is really getting out there when the headline is "Hand Sanitizer Not Antibacterial Soap"? Other health organizations report that hand sanitizer is LESS effective than conventional soap. PLEASE PLEASE PLEASE FOCUS ON HAND WASHING. MAKE HEADLINES: "WASH HANDS".

Some people are sensitive to germicides : they irritate the flesh with repeated use. This cannot be good for maintaining the barrier to infection : or for encouraging continual use of toxic compounds.
I would expect the futility of trying to disinfect everything everywhere would have another side effect : as overuse of antibiotics led to resistant strains, persistant flooding contaminated areas will lead to culturing germicide resistant strains.
Washing itself merely cleans : and should not cause unwanted side effects.

Thanks for the words of caution about hand sanitizers. The commenters are correct to emphasize that hand sanitizers (although safer than antibacterial soap) are really for use when you can't easily get to a sink with running water. So old fashioned hand washing really is the best defense.

Fortunately there don't appear to be antimicrobial resistance problems with the alcohol-based products, since they work by physically drying out the microbes, so germicide resistance isn't a problem. But of course, that drying action is precisely why some people get skin irritation from these products.
