EnterovirusWe are currently seeing children and adolescents with infections caused by the enteroviruses, a group of viruses that often cause illness during the summer and the early fall months. The commonly used term "enterovirus" includes the coxsackie viruses, the echoviruses, and the enteroviruses. These viruses often cause a fever, and also may cause a rash, respiratory or cold symptoms, and vomiting with diarrhea. Hand-foot-mouth disease, a rash that involves those areas of the body, is a common enteroviral infection that occurs in children. More serious illnesses that are caused by these viruses include meningitis, heart infections, and eye infections. For mild illnesses caused by the enteroviruses, the best treatment is adequate rest, plenty of fluids, and fever control.
