Smooch! You may have heard mononucleosis,
or mono, called the kissing disease. That's because someone who has this infection can
pass it to others by kissing them. But it also can spread when people with mono share
toothbrushes, straws, or anything that might have their saliva
Mono can make someone feel super tired and also has a lot of the same symptoms
as the flu — a fever, sore throat, and headaches. Kids who have mono need to
rest a lot to get better.
