Spatiotemporal Trends in Group A Streptococcal Pharyngitis in the United States.

ABSTRACT:

Background

Group A Streptococcus (GAS) causes an estimated 5.2 million outpatient visits for pharyngitis annually in the United States, with incidence peaking in winter, but the annual spatiotemporal pattern of GAS pharyngitis across the United States is poorly characterized.

Methods
