Clin Infect Dis. 2020 Mar 17;70(7):1478-1481. doi: 10.1093/cid/ciz716.

Abstract

Using population-based surveillance data, we quantified the secondary invasive group A Streptococcus disease risk among household contacts. The disease risk in the 30 days postexposure to an index-case patient was highest among individuals aged ≥65 years, versus the annual background incidence of all ages.

Keywords: Streptococcus pyogenes; disease transmission; epidemiology; group A Streptococcus; surveillance.
