Prevalence of group A β-hemolytic streptococcal throat carriage and prospective pilot surveillance of streptococcal sore throat in Ugandan school children

The GAS pharyngeal carriage rates seen in Uganda (15.9%, 95% confidence interval 12.8-19.5%) are higher than the most recent pooled results globally, at 12% (range 6-28%). Additionally, pilot data suggest a substantially higher percentage of sore throat that was GAS-positive (41.8%) compared to pooled global rates when active recruitment is employed.
