Streptococcal infection and the chronic carrier state.

Group A beta-hemolytic streptococcal pharyngitis is an extremely common problem for the family physician. Clinical signs are not reliable in making the diagnosis. Infections with few or no symptoms are common. Throat culture is the best aid to diagnosis. One-quarter or more of family contacts harbor the organism. Good mamagement includes accurate bacteriologic diagnosis, adequate use of the appropriate penicillin preparation, repeat cultures, treatment of family members, if indicated, and recognition of the chronic carrier state.
