Entry description:

Data showing Invasive Group A Streptococcus (iGAS) infections in England has been added to the dashboard.

The dashboard now shows the weekly count and the monthly rate per 100,000 population of iGAS cases.

Cases of iGAS are formally diagnosed from positive microbiological diagnostic test results. All positive samples are reported to the UKHSA Second Generation Surveillance System (SGSS).

Group A Streptococcus (also known as GAS, group A strep, strep A, and Streptococcus pyogenes) is a bacterium which can colonise the throat, skin and anogenital tract.
