Causes, incidence, and risk factors | 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 lesions. The lesions 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 lesions. The incidence of herpangina is unknown, but it is a common childhood infection. A history of herpangina at school or in the neighborhood increases the chances your child will develop the illness. |
Symptoms | Lesions in mouth, as described above Similar lesions on feet, hands, buttocks Fever Loss of appetite Sore throat , or painful swallowing |

Calling your health care provider | Call your health care provider if the fever , sore throat , or throat lesions persist beyond 5 days, if your child is having trouble drinking liquids or looks dehydrated, or if the fever becomes excessive or persistent. |
