Abstract

We used a combination of local, comprehensive strain surveillance and bacterial whole-genome sequencing to identify potential transmission events of group A streptococcus (GAS) in Houston, TX, USA. We identified pharyngeal and skin and soft tissue sources of infection as having important roles in community GAS transmission, including invasive diseases.

Keywords: group A streptococcus; invasive disease; transmission; whole-genome sequencing.
