What Does Contagious Mean?
There's a good reason your parent tells you to cover your mouth when you sneeze or cough! When an illness is contagious, it means you can catch it from another person. Contagious sicknesses include colds and the flu. Cover your mouth when you sneeze or cough, and you'll help prevent bacteria and viruses from getting in the air. It's also important to wash your hands, whether you are sick or well, to prevent the spread of germs on things that other people might touch.
