# Routine genomic surveillance in a military healthcare facility detected a community-based Group A Streptococcus outbreak associated with grappling sports

## TL;DR

Genomic surveillance at a military hospital identified a Group A Streptococcus outbreak linked to grappling sports.

## Contribution

Demonstrates how genomic surveillance can detect community-driven outbreaks beyond hospital settings.

## Key findings

- Outbreak of emm92/ST82 Streptococcus pyogenes was detected through genomic surveillance.
- Most cases were linked to grappling sports, with one case from household transmission.
- Routine surveillance revealed community-based transmission patterns.

## Abstract

An outbreak of emm92/ST82 Streptococcus pyogenes was detected through prospective genomic surveillance at a military treatment facility. Twenty-one of twenty-six patients had confirmed epidemiological links to grappling sports. One case resulted from household transmission. The benefits of routine surveillance extend beyond the hospital environment enabling the detection of community-driven transmission.
