Eosinophilic inflammation, coronavirus disease 2019, and asthma: Are inhaled corticosteroids the missing link?

Abstract

We congratulate Dr Ho et al1 on their work that further clarified the relationship between blood eosinophils, asthma, and the risk of severe coronavirus disease 2019 (COVID-19). They leveraged data from their large clinical network, which unlike others,2,3 includes outpatients diagnosed as having COVID-19. The authors effectively reveal that in asthma and in health, having a raised blood eosinophil count is protective against severe COVID-19 and associated mortality.
