Asthma is the most common chronic childhood condition and is a risk factor for severe respiratory viral infections. Thus, early during the coronavirus disease 2019 (COVID-19) pandemic there was concern that children with asthma would be at risk for severe COVID-19 illness and that asthma control could worsen as a result of the pandemic. This article seeks to summarize what was learned in the early stages of the pandemic about the impact of COVID-19 on children with asthma. We review evidence from several studies that demonstrated a significant decline in asthma morbidity in the first year of the pandemic. Additionally, we describe several potential mechanisms that may explain the reduced frequency in childhood asthma exacerbations as well as review lessons learned for future management of childhood asthma. While the COVID-19 pandemic initially brought uncertainty, it soon became clear that the pandemic had several positive effects for children with asthma. Now we can apply the lessons that were learned during the pandemic to re-examine asthma care practices as well as advocate for best approaches for asthma management.
