Pediatric asthma exacerbations during the COVID-19 pandemic

The authors found that in 2020, the District of Columbia did not experience the typical “September asthma epidemic” of exacerbations seen in past years.

In the United States, pediatric asthma exacerbations typically peak in the fall due to seasonal factors such as increased spread of common respiratory viruses, increased exposure to indoor aeroallergens, changing outdoor aeroallergen exposures and colder weather. In early 2020, measures enacted to reduce spread of the coronavirus (COVID-19) — such as social distancing, quarantines and school closures — also reduced pediatric respiratory illnesses and asthma morbidity. Children’s National Hospital immunologist and allergist William J. Sheehan, M.D., and colleagues sought to determine if these measures also affected the 2020 fall seasonal asthma exacerbation peak in Washington, D.C.

The authors found that in 2020, the District of Columbia did not experience the typical “September asthma epidemic” of exacerbations seen in past years. Emergency department visits, hospitalizations and intensive care unit admissions for asthma during the 2020 fall season were significantly reduced compared to previous years.

The authors conclude that, “this is likely due to social distancing, quarantines and school closures enacted during the pandemic. This is a small silver lining in a very difficult year. As 2021 brings optimism for gradual improvements of the pandemic, careful monitoring is necessary to recognize and prepare for childhood asthma morbidity to return to pre-pandemic levels.”
