Herpangina
Symptoms of Herpangina
Herpangina is characterized by sudden onset of fever with sore throat, headache, anorexia, and frequently neck pain. Infants may vomit. Within 2 days after onset, up to 20 (mean, 4 to 5) 1- to 2-mm diameter grayish papules develop and become vesicles with erythematous areolae. They occur most frequently on the tonsillar pillars but also on the soft palate, tonsils, uvula, or tongue. During the next 24 hours, the lesions become shallow ulcers, seldom>5 mm in diameter, and heal in 1 to 7 days. Complications of herpangina are unusual. Lasting immunity to the infecting strain follows, but repeated episodes caused by other group A coxsackieviruses or other enteroviruses are possible.
