Did you know that some viruses and bacteria can live up to two hours or more on surfaces like cafeteria tables, doorknobs and desks?

One of the best ways to stop the spread of germs is to cover your mouth and nose when sneezing or coughing, and clean your hands often. Remind your children to practice healthy habits too. The CDC recommends washing your hands with soap and warm water for 15 to 20 seconds. One easy way to gauge that amount of time is to sing the "Happy Birthday" song to yourself twice.
