Prevalence of Group A β-hemolytic streptococcal throat carriage and prospective pilot surveillance of streptococcal sore throat in Ugandan school children
International Journal of Infectious Diseases Jan 25, 2020
DeWyer A, Scheel A, Webel AR, et al. - Given that 92% of group A β-hemolytic streptococcus (GAS) related acute pharyngitis occur in low-resource settings, researchers sought to assess the acute streptococcal pharyngitis burden in low resource settings so that serious poststreptococcal complications, rheumatic fever and its long-term sequel rheumatic heart disease, could be prevented. From March to April 2017, two studies in school-aged children (5 – 16 years) were performed: a cross-sectional study of streptococcal pharyngeal carriage followed by a prospective cohort study of streptococcal sore throat over 4 weeks. Outcomes revealed an overall prevalence of GAS carriage of 15.9% (79/496) indicating higher group-A strep rates in Uganda than results pooled globally [12% (range 6-28%)]. Further, pilot data infer a substantially higher percentage of sore throat that was GAS positive (41.8%) compared with pooled global rates when active recruitment is exercised. Group-A Strep was universally susceptible to penicillin and sulfamethoxazole/trimethoprim
