Therefore, studies are needed to characterize the precise interaction of chronic airway diseases (such as asthma) and of biologics (such as Omalizumab) with SARS-CoV-2 infections in humans. We report a case of a 52-year-old man with severe allergic asthma treated with Omalizumab with no evidence of an asthma exacerbation, loss of asthma control or pneumonia during symptomatic COVID-19 disease. We hypothesize that the underlying disease (allergic asthma) or the antibody used for treatment (Omalizumab), or both, might have exerted protective effects. ./cache/cord-336026-x02f7byo.txt ./txt/cord-336026-x02f7byo.txt
