Increase in Invasive Group a Streptococcal Infections in Children in the Netherlands, A Survey Among 7 Hospitals in 2022.

Following an increase in notifiable invasive group A streptococcal (iGAS) infections in the Netherlands, we conducted a survey among 7 hospitals. Pediatric iGAS case numbers were 2-fold higher between July 2021 and June 2022 versus pre-COVID-19. A sharp increase occurred early 2022, most pronounced in <5 years old and for diagnoses empyema and necrotizing fasciitis. This recent pediatric iGAS surge warrants investigation and vigilance.
