Herpangina is caused by Coxsackie virus, typically Coxsackie group A viruses. Herpangina is characterized by mouth ulcers, but a high fever, sore throat, and headache may precede the appearance of the sores. The sores are generally ulcers with a white to whitish-gray base and a red border -- usually on the roof of the mouth and in the throat. The ulcers may be very painful. Generally, there are only a few sores. The number of cases of herpangina is unknown, but it is a common childhood infection. Cases of herpangina at school or in the neighborhood increase the chances your child will develop the illness.
