SUMMARY

Washing hands is essential for reducing germ transmission, contrary to claims made by some individuals. Key arguments against handwashing include the transfer of germs from faucet levers and the omnipresence of germs on surfaces. However, studies and health guidelines, such as those from the CDC, emphasize that proper hand hygiene significantly lowers infection risk. The discussion highlights the importance of understanding infection control practices, especially in public settings.

PREREQUISITES
  • Understanding of basic microbiology concepts related to germs and bacteria.
  • Familiarity with infection control principles in healthcare settings.
  • Knowledge of public health guidelines, particularly those from the CDC.
  • Awareness of common surfaces that harbor germs, such as cash and faucet handles.
NEXT STEPS
  • Research the CDC guidelines on handwashing and infection prevention.
  • Explore studies on the effectiveness of hand hygiene in reducing illness transmission.
  • Learn about the role of surfaces in germ transmission and cleaning protocols.
  • Investigate the microbiome and its relationship with human health and hygiene practices.
USEFUL FOR

Public health professionals, healthcare workers, educators, and anyone interested in understanding the importance of hand hygiene in preventing infections.

A good friend of mine (a computer engineer to be exact!) said this over a beer:

Washing hands doesn't really get rid of germs. There are lots of reasons why:

i.) If your hands are dirty and have germs on them to begin with, you have to touch the faucet lever (assuming not automatic) to turn on the water. That transfers those germs to the lever. When you're done washing, you're simply touching the same lever where there are germs and retrieving those same germs.

ii.) Germs are everywhere. You can't hide from them. They live on your skin and on surfaces all over the place. If you've handled money ever in your life - which is everyone - then you've likely touched some really nasty germs. Think of where those dollars and hands touching them have been. So, would you wash your hands every single time you've paid using cash? Of course, not, he says.

iii.) This reason pertains specifically to using the restroom. If you know yourself well and know that you clean yourself very well at home, then washing your hands in a public bathroom is unnecessary. See i.) for the reason why. Just use it and go. If you're already keeping yourself clean, then you're probably touching worse stuff by trying to wash. So, it's better to not wash after using the restroom.

At first, I was like nawww, that's some nasty stuff there. But, then, I started thinking about it and had a hard time refuting him.

Is there any validity to his argument?

I would think twice about accepting his dinner invitation.

You can never really get rid of all bugs but sometimes it's the quantity you are exposed to that matters.
