Patients with asthma do not appear to have an elevated risk for severe SARS-CoV-2 pneumonia, nor does such pneumonia seem to induce severe asthma exacerbation, according to researchers in France.

Asthma is listed as a risk factor for severe COVID-19 illness by the US Centers for Disease Control and Prevention, and other respiratory viral infections are known to be associated with severe asthma exacerbation.
