SARS-CoV-2 co-infection with influenza viruses, respiratory syncytial virus, or adenoviruses

Measures to reduce transmission of SARS-CoV-2 have also been effective in reducing the transmission of other endemic respiratory viruses.1,2 As many countries decrease the use of such measures,2 we expect that SARS-CoV-2 will circulate with other respiratory viruses, increasing the probability of co-infections.1,3 The clinical outcome of respiratory viral co-infections with SARS-CoV-2 is unknown.
