What is herpangina?

Herpangina is an acute, virally induced, self-limited illness often seen in young children during the summer months. Affected children usually complain of mouth sores and fever. It is caused by a number of viruses, all part of the enterovirus family, coxsackievirus being the most common. Most children develop a high fever and complain of a sore throat. They then develop vesicles (blisters) or ulcers (sores) at the back of the throat and palate (also called an enanthem). Children, especially younger children, may refuse to eat or drink because of the pain and are at risk for developing signs and symptoms of dehydration.

What causes herpangina?

Several common Coxsackie A viruses can cause herpangina, although a number of other enteroviruses have also been implicated. The viruses are usually spread via the "fecal-oral route" (contamination of hands and other surfaces with fecal matter) or via the "respiratory route" (air droplets from coughing or sneezing). Contact with mucous of an individual infected with one of these viruses is usually all that is needed to contract the illness. In fact, half of individuals infected with some of these enteroviruses remain asymptomatic (having no symptoms) throughout, which makes preventing transmission more difficult.
