Group A Streptococcus invasive infection in children: Epidemiologic changes and implications.

Group A Streptococcus (GAS) can cause a broad array of clinical manifestations and complications. Recently, in post COVID-19 postpandemic months, there has been an increased incidence and severity of invasive infections in the pediatric age group in Spain and other European countries with high morbidity, affecting mostly to young children, associated with seasonal peaks in incidence of viral respiratory pathogens. The increased in incidence and severity has not been associated with predominant GAS strains, but rather to the lack of immunity to both GAS and common viral respiratory infections due to isolation measures to prevent COVID-19. Due to the nonspecific initial clinical manifestations a high index of suspicion is necessary in order to initiate a prompt medical and surgical treatment when necessary to improve the outcome. Prevention strategies are needed as well as continuous microbiological surveillance of iGAS strains.
