I actually had been wondering about that. Seems we didn't hear too much about asthma after a while. One of my sister-in-laws has asthma though it's not severe at all.
My young niece (8) has severe asthma and was hospitalized with pneumonia in January for 10 days. Her pulmonologist told my sister that she was very concerned about my niece catching Covid, not because of her asthma, but because of her susceptibility to developing pneumonia with almost every upper respiratory infection (she has had pneumonia at least 6 times). She says the asthma isn't a risk factor itself. My niece has a spinal curve that compresses her left lung, leading to issues allowing it to fully expand so when she gets sick, infections settle in the lung because she can't cough it out efficiently.
