There has been cluster of confirmed cases of invasive Group A Streptococcal infection (iGAS) in people in People Who Inject Drugs (PWID) in central Bristol. Please see the Health Security Agency letter.for details.

Red Flags

Invasive GAS (iGAS) is another infection caused by GAS, that is much rarer than scarlet fever. It occurs when GAS is isolated from a normally sterile body site, such as the blood (2).

Occasionally these infections can be extremely severe.

People at increased risk of Invasive Group A Strep (iGAS)

  • At extremes of the age range, such as the very young and old, or postpartum women.
  • Who are immunocompromised, immunosuppressed, or with other comorbidities.
  • With concurrent chickenpox or influenza.
  • Who inject drugs or are alcohol dependent.

Scarlet Fever

Scarlet fever is an infectious disease caused by Group A Strep (GAS) and is  mainly a childhood disease, with around 90% of cases occurring in children under 10 years old. People of all ages can also catch scarlet fever, but the disease is much less common in adults (1).

Please see the Scarlet Fever/ Group A Strep (children and young people) page for further information.
