Herpangina is a viral illness characterized by ulcers and lesions (sores) inside the mouth, sore throat, and fever. Even though the name sounds like herpes, almost all of the many viruses that cause it are coxsackieviruses or other enteroviruses -not herpesvirus. There are actually many different types of Coxsackie virus which cause several different diseases; herpangina is cause by only one or two of these “serotypes”. It is typically occurs during the summer and frequently in children, but also young adults. Various enteroviruses cause the condition. If similar shallow blister-like lesions appear on the palms or soles, it may be called hand, foot, and mouth disease. The lesions in the mouth are round macules (nonraised spots) about 2 mm (0.1 inch) in diameter, occurring predominantly on the soft palate and tonsils. Usually, herpangina is produced by one particular strain of coxsackievirus A, but it can also be caused by coxsackievirus B or echoviruses. It is most common in children.
Herpangina is an acute febrile illness associated with small vesicular or ulcerative lesions on the posterior oropharyngeal structures. The herpangina virus can be spread by saliva and mouth-to-mouth contact, as well as by contact with an infected person’s stools. It usually takes 3-6 days after exposure to become infected. Fresh water sources (eg, lakes) may act as a reservoir for transmission. A diagnosis can be made from clinical signs and symptoms, and treatment consists of minimizing the discomfort of symptoms. While it is possible to have these infections more than once, it is relatively rare, and most adult caregivers are not at risk of contracting the disease from affected children.
