Herpangina (say "HUR-pann-JY-nuh") is an illness that is caused by a virus. It causes sores inside the mouth, a sore throat, and a high fever. Adults usually do not get it. Herpangina easily spreads to other children through exposure to a sick child's runny nose or saliva.
While herpangina can make your child feel very ill for a few days, this illness usually clears up within a week.
