Herpangina is a viral throat infection caused by, usually, a Coxackie A virus. It usually affects infants and young children. An infected child will have 2-4 days of high fever and a sore throat for less than a week. Typically, they will develop between 2 and 6 ulcers on the back of the throat. They start as bumps, then blister and then turn into ulcers of about 2-4 mm in size.

There is no specific treatment since it goes away on its own. Comfort measures include tylenol or ibuprofen and cold things such as popsicles, frozen yogurt or fruit smoothies. If you have questions or are concerned, have your child seen by a health care provider.
