Asma e COVID-19: Atualização

Abstract

The relationship between asthma and COVID-19 is not completely understood yet. We here review the publications on the interplay between these two diseases, as available on the article submission day. The preliminary results did not find a conclusive association between asthma and an increased risk for SARS-CoV-2 infection or severe COVID -19. However, important differences have been found between studies performed in various locations. SARS-CoV-2 infection does not seem to cause asthma exacerbations, and certain typical asthma signs like wheezing were not described in COVID -19 patient series. The susceptibility and risk for COVID -19 in asthma patients may vary according to the patients’ age, asthma severity, asthma control, phenotypes/endotypes, or current treatment. Studies analysing COVID--19 specifically in asthma patients will be required to evaluate the real impact of COVID--19 in asthma.
