Recurrent streptococcal pharyngitis. Using practical treatment options to interrupt the cycle.

Most family physicians have seen cases like this: A child is brought in with pharyngitis, which responds to antibiotic therapy. Soon the mother comes in with fever and a sore throat. She also recovers with therapy, but soon she's back with the child, who has pharyngitis again. Dr Ruoff explains why streptococcal infection recurs and how to assess probability so treatment can be started without waiting for test results. He also discusses alternatives to standard penicillin therapy, some of which may avoid the problems of noncompliance.
