Herpangina is a viral illness in which ulcers and sores (lesions) form inside the mouth, and there is a sore throat and fever.
Causes, incidence, and risk factors
Herpangina is typically caused by Coxsackie group A viruses.
The number of cases of herpangina is unknown, but it is a common childhood infection. It is most often seen in children ages 3 - 10, but it can occur in any age group. Cases of herpangina at school or in the neighborhood increase the chances that your child will develop the illness.
