We might have feared a multiplied effect of a co-infection with the influenza A virus and SARS-CoV-2, responsible for the COVID-19 disease, but this research from New York University is reassuring: it suggests , “on the contrary”, that co-infection with influenza A appears to inhibit coronavirus replication in SARS-CoV-2 infection. In other words, if the coinfection of SARS-CoV-2 and influenza A virus does not alter the trajectory or severity of influenza A virus, regardless of when the host contracts the virus of influenza A first, the response to this infection can significantly suppress the virulence of SARS-CoV-2, according to these data published in the Journal of Virology, a journal of the American Society for Microbiology.
