Philadelphia, August 20, 2020 - Philadelphia and its surrounding counties issued a series of "stay-at-home" orders on March 17, 2020 in an effort to curb the spread of COVID-19. In the months that followed, Children's Hospital of Philadelphia (CHOP) saw a marked decrease in healthcare visits for both outpatient and hospitalized asthma patients. New research from CHOP and the Hospital of the University of Pennsylvania suggests the cause may have been fewer rhinovirus infections due to masking, social distancing, and hygiene measures.
Researchers reviewed the 60 days leading up to March 17, 2020 and compared them to the 60 days following stay-at-home orders. They found a 60% decrease in the total daily asthma healthcare visits across CHOP's hospital and Care Network, which includes more than 50 primary care offices, specialty care and surgical centers, urgent care centers, and community hospital alliances throughout Pennsylvania and New Jersey.
