Disease control programs in the United States. Control of streptococcal and poststreptococcal disease.

Programs administered by health departments and heart associations for control of streptococcal and poststreptococcal disease differ greatly from state to state. The year 1974 was used as a representative year when studying the variety of state policies and programs regarding surveillance of streptococcal disease, primary and secondary prevention of rheumatic fever, and prevention of poststreptococcal glomerulonephritis. A uniform national policy for streptococcal control is desirable but should be based on evidence not now available concerning the impact of various elements of control programs on morbidity and mortality.
