On June 26, 2025, the Department of Public Health (DPH) issued a clinical advisory in response to the rising number of invasive Group A Streptococcus (GAS) infections and reported clusters in long-term care facilities across the Commonwealth. GAS infections can be life-threatening and may present as a range of serious clinical syndromes, including bacteremia, pneumonia, meningitis, osteomyelitis, septic arthritis, peritonitis, necrotizing fasciitis, and toxic shock syndrome (TSS). The advisory includes critical information, guidance, and recommendations to help mitigate the spread of GAS.
Given the continued increase in GAS cases in Massachusetts, it is essential for nursing facility leadership and front-line staff to prioritize strict infection prevention and control practices during resident care. The clinical advisory outlines key strategies to reduce transmission risk, and all facility staff – including contracted personnel – should receive training on GAS infection risks and appropriate infection control protocols.
Any newly identified cases of invasive GAS in LTCF residents or staff should be reported to the MDPH Division of Epidemiology at (617) 983-6800 which is available 24/7.
