Please note that Covid19 is so new that there is no evidence that chronic use of inhaled steroids for asthma can increase the risk associated with Covid19 infection. However, the mildly immuno-suppressive effects caused by chronic steroid use, including inhaled and intranasal steroids, have been long known. So this is a relevant concern and a good topic to discuss with the prescribing physician or specialist.
