When an illness is contagious, it means you can catch it from another person. How do you know when an illness is in the contagious stage? Most viral illnesses are contagious before any symptoms start. So an infected person can spread a virus before feeling sick. This makes it almost impossible to stop the spread of infections.
Contagious diseases (such as the flu, colds, or strep throat) spread in several ways, such as through direct physical contact, like touching or kissing a person who has the infection. Another way is when an infectious germ travels through the air after someone nearby sneezes or coughs.
Some childhood rashes — such as hand, foot, and mouth disease, chickenpox, and ringworm — spread through skin-to-skin contact. So kids with a rash should avoid contact with others until the spots crust over.
The best way to fight germs and keep them from spreading is to make sure that kids (and adults!) wash their hands well and often, especially:
- after playing outside
- before eating
- after going to the bathroom
- after coughing or sneezing
Also, teach the kids to cover their coughs and sneezes. If they don't have a tissue handy, they should cough or sneeze into an elbow, not their hands.
