Herpangina is a viral illness in which ulcers and lesions (sores) form inside the mouth, and there is sore throat and fever.

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.

TopSymptoms
Fever
Headache
Loss of appetite
Sore throat, or painful swallowing
Ulcers in the mouth and throat, and similar sores on the feet, hands, and buttocks
The ulcers usually have a white to whitish-gray base and a red border. They may be very painful. Generally, there are only a few sores.
Tests are not normally necessary. Diagnosis can usually be made from the history and physical examination.

The symptoms are treated as necessary:
Acetaminophen (Tylenol) or ibuprofen (Motrin) by mouth for fever and discomfort as the doctor recommends
Increased fluid intake, especially cold milk products
Non-irritating diet (cold milk products, including ice cream, are often the best choices during herpangina infection. Fruit juices are too acidic and tend to irritate the mouth sores.)
Topical anesthetic agents for the mouth (these may contain benzocaine or xylocaine and are usually not required)
The illness normally clears up within a week.

Call your health care provider if:

Fever, sore throat, or mouth sores last for more than 5 days
Your child is having trouble drinking liquids or looks dehydrated
Fever becomes very high or does not go away

Coxsackie virus is transmitted by contamination with feces, which means you can catch the virus by touching your mouth or eating without thoroughly washing your hands. Good handwashing practices can help prevent transmitting most viruses.
Being aware of other cases of herpangina in your neighborhood or school may allow earlier diagnosis.
It looks like exposure to the Herpangina virus will present symptoms in the regions metioned above, not in the genetalia as is the case with the Herpes Virus.  For further information on the Herpes Virus, you can post your question on the Herpes Forum.
