2) Spreading or Catching Colds and Flu
If you have a cold or the flu, you can easily spread germs by not washing your hands enough. While it’s true these germs may also be airborne, washing your hands will prevent you from spreading germs via your hands. You can also leave germs on surfaces that other people may touch and subsequently catch your illness. Likewise, you can catch germs and become ill from touching surfaces and not washing your hands afterwards. If you want to prevent brining germs home with you, the rule of thumb is to wash your hand as soon as you get in the door. That way, if any germs have hitched a ride on your hands, they won’t be taking up residence in your home or your body. If you’ve already caught a cold or flu, you should always wash your hands after you touch your nose or mouth.
