The New York State Department of Health (NYSDOH) reports statewide, including New York City, there have been over 450 cases of invasive group A streptococcal infections reported during the first three months of 2023. This is almost twice as many as the average for these same three months in the previous five years.
The increase is reported primarily among persons aged 65 and older, though small increases are being seen in children.
NYC and NYS providers have reported severe outcomes of invasive group A streptococcal infections, including necrotizing fasciitis, streptococcal toxic shock syndrome, and death. Clinical syndromes for recently reported pediatric invasive group A streptococcal cases and non-invasive group A streptococcal cases include acute hypoxic respiratory failure secondary to pneumonia, empyema, osteomyelitis, and septic arthritis, among others
Recent pediatric invasive group A streptococcal infections and non-invasive group A streptococcal infection cases in NYC and NYS have been associated with respiratory infections due to parainfluenza, rhinovirus, enterovirus, influenza, and human metapneumovirus, among other viruses. Concurrent or preceding viral infections, including varicella (chickenpox), may increase risk for invasive group A streptococcal infection.
