What is the cause of herpangina?

Herpangina is primarily caused by the Coxsackie virus, which is a member of the enterovirus family. This viral infection is most common in children and typically presents with a sudden onset of fever, sore throat, and small, painful vesicles or ulcers in the mouth and throat. The Coxsackie virus can lead to inflammation and lesions that are characteristic of herpangina. Understanding the etiology is crucial for diagnosis and management, as it differentiates herpangina from other viral infections that may cause similar symptoms, such as those caused by herpes simplex virus or other viruses mentioned. Coxsackie virus is particularly notable for causing outbreaks in schools and daycares, often during summer and early fall, when the virus is more prevalent.
