washing hands with soap by UofL Health Louisville KY

Did you know?

  • A person has more bacteria on their body than there are people in the United States.
  • On each square centimeter of your skin there are about 1,500 bacteria.
  • There are about 21,000 germs per square inch on work desks.
  • There is an average of 229,000 germs per square inch on frequently touched faucet handles.

The worst germ hiding places include: work desk, kitchen sink (worse than bathroom), dishcloth/sponge, garbage can, refrigerator, bathroom doorknob, keyboards, escalator handrails, shopping cart handles, picnic tables, light switches, remote controls, toys, bathroom cups, pet cages, and writing utensils.

Hand washing prevents the spread of germs, and most diseases can be prevented with proper hand hygiene.

Don’t forget to wash your hands with soap and warm running water.
