Thoroughly wash your hand after going to the bathroom.
Toothbrushes should be changed monthly and discarded after
a cold or other illness.
Parents should teach children not to share items such as bottles,
cans of soda, or drinking glasses with anyone (and parents
shouldn't share drinks with their children). Sharing liquids
is a super-quick way to transmit colds, infectious mononucleosis,
and other illnesses.
Teach healthy habits in creative ways with songs, games, or
rewards. For example, to teach children how to blow their
noses, have them practice by moving a feather on a table without
blowing through their mouths. Or use a rhyme when a child
forgets to cover her nose and mouth when she sneezes: Cover
your nose and mouth when you sneeze, please!
