Asthma isn’t on the list of factors that are associated with negative Covid-19 outcomes.
Comorbidities that at any age that put individuals are high risk of Covid-19 complications:
cancer, chronic kidney disease, COPD, immunocompromised (for any reason), obesity (BMI>30), type 2 diabetes, sickle cell diseases, and ** serious** heart disease (i.e. heart failure, cardiomyopathies, coronary artery disease.
The CDC says that there is insufficient evidence that moderate to severe asthma causes an increased risk of negative outcomes from Covid-19. A history of past respiratory infections is also not an indicator of elevated risk. (Unless the individual has COPD.)
(I just had this discussion with both my PCP and my daughter [an ER physician at one of the nation’s top research hospitals where they’ve treated tens of thousands of Covid-19 patients].)
