Clinical practice. Streptococcal pharyngitis.

摘要

A 10-year-old girl presents with a sore throat and fever that has lasted for 1 day. She appears flushed and moderately ill. Physical examination reveals a temperature of 39degC, tender bilateral anterior cervical lymph nodes that are 1 to 2 cm in the greatest dimension, and erythema and whitish-yellow exudate over enlarged tonsils and the posterior pharynx. A rapid antigen-detection test from a throat-swab specimen is positive for group A streptococcus. How should the patient be evaluated and treated?
