A cluster of Invasive Group A Streptococcus (iGAS) cases has been identified in Camden and Islington, according to a health protection update presented at the Camden Health and Wellbeing Board meeting on Wednesday, 9 July 2025.

The UK Health Security Agency (UKHSA) informed the board of seven iGAS cases identified over a three-month period between March and May 2025. This cluster is being investigated to determine if it represents a significant deviation from the typical incidence rate in the area1. The cases were reported among people who inject drugs and people experiencing homelessness.

According to the report pack for the meeting, no direct links have been established between the cases. However, due to the vulnerability of people who inject drugs to a wide range of infections, communications have been shared to raise awareness about Group A Strep and its signs and symptoms. Messages have also been disseminated to remind people who inject drugs about infection prevention measures during injection2.
