Found this enlightening article in Prevention Magazine online written by Alyssa Shaffer. It adds a few more places that I have to worry about germs.

1. Kitchen Faucet

That metal aeration screen at the end of the faucet is a total germ magnet.

Running water keeps the screen moist, an ideal condition for bacteria growth. Because tap water is far from sterile, if you accidentally touch the screen with dirty fingers or food, bacteria can grow on the faucet, explains microbiologist Kelly Reynolds, PhD, an associate professor of community environment and policy at the University of Arizona College of Public Health. Over time, bacteria build up and form a wall of pathogens called biofilm that sticks to the screen. “Eventually, that biofilm may even be big enough to break off and get onto your food or dishes,” she notes.

Fecal bacteria can survive on hands for hours at a time, especially in warm temperature away from sunlight. Germs were easily transferred by touch on the doorknob, food, and even cell phones. Germs can then move on to someone else.

Every year, children under age five died by pneumonia and diarrheal diseases, which can actually be prevented by the simple act of washing hands with soap.

In developed countries, wash hands with soap helps people to prevent the spread of viral infections, such as norovirus, rotavirus, and influenza
