Effects of public health interventions designed to limit viral transmission on asthma features. Public health interventions designed to limit viral transmission (masking, social distancing, school closures, etc) were associated with a restructuring of asthma care delivery including a reduction in in-person encounters and an increase in VTM-based care. Overall asthma encounters were reduced, as were systemic steroid prescriptions. Changes in RV infections, but not pollution levels, may have contributed to these trends.
