The SARS-CoV-2 Pandemic and Asthma: What We Have Learned and What is still Unknown

The SARS-CoV-2 pandemic has brought new insights into the immunological intricacies of asthma. In this review, we discuss the epidemiology of asthma in patients infected with SARS-CoV-2 and the risk of severe infection. Type 2 inflammation had an overall protective effect against SARS-CoV-2 infection by various mechanisms summarized in this review. Asthma, intranasal, and inhaled corticosteroids decreased the ACE2 receptor, an important receptor for SARS-CoV-2 entry into host cells. We summarize the nuances of treatment of type 2 inflammation despite its underlying protective effects.
