Brown and his colleagues analyzed 562 people recently tested for COVID-19 at Stanford Health Care's Marc and Laura Andreessen Emergency Department. Forty-nine of those people tested positive for infection with SARS-CoV-2.
Of the 562 people, 517 were also tested for the presence of other common respiratory viruses, such as influenza A and B, respiratory syncytial virus, rhinovirus, adenovirus and several types of pneumonia. One hundred and twenty seven received a positive result for one of these other respiratory viruses.
Of the people tested for both SARS-CoV-2 and other respiratory viruses, eleven people—or about 22% of the 49 confirmed COVID-19 cases and 8.7% of the 127 people with other respiratory viruses—were found to be co-infected with both kinds of viruses. End quote
