Impact of the COVID-19 Pandemic on Pediatric Invasive Group A Streptococcus Infections in the United States

What to know

  • Presentation Day/Time: Friday, April 25, 10:55 am–12:20 pm
  • Presenter: Veena Ramachandran, MD, MPH, EIS officer assigned to the National Center for Immunization and Respiratory Diseases, Division of Bacterial Diseases

What did we do?

  • We used CDC’s Active Bacterial Core surveillance (ABCs), a multistate population- and laboratory-based surveillance system, to assess changes in pediatric invasive group A Streptococcus (GAS) incidence and clinical presentation, including during the COVID-19 pandemic.

What did we find?

  • During 2004-2022, in total 2,524 pediatric invasive GAS cases were identified.
  • Compared with expected incidence, observed iGAS incidence was 52%, 74%, and 27% lower in 2020, 2021, and 2022, respectively. Observed incidence in November and December 2022 exceeded expected incidence by 117%.
  • Pneumonia incidence decreased more than the other clinical syndromes during 2004–2019 and 2021 and increased more than the other syndromes during 2021 and 2022.

Why does it matter?

  • Descriptions of changes in pediatric iGAS infections during the COVID-19 pandemic are limited.
  • Nonpharmaceutical interventions implemented during the COVID-19 pandemic to help mitigate viral transmission may have helped decrease transmission of invasive GAS. Following the relaxation of these interventions, cases of invasive GAS rapidly increased.
  • The continued prevalence and recent rapid rise of invasive GAS highlights the need to accelerate development of preventive strategies to stem further increases in invasive GAS disease.
