‘Tripledemic:’ FLU, COVID-19 and RSV.

By early winter in 2022, RSV, flu, and COVID-19 were surging more or less simultaneously. It is likely that this is going to be the new normal with each year seeing the co-circulation and seasonality of RSV, flu, and COVID-19. Identifying which virus is causing an infection is critical to appropriate medical management and necessary for properly tracking outbreaks.

 

Trend: FDA Recommends At-home COVID-19 Serial Rapid Test

February 24, 2023, the U.S. Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for the first over-the-counter (OTC) at-home diagnostic test that can differentiate and detect influenza A and B, commonly known as the flu, and SARS-CoV-2, the virus that causes COVID-19.

 

The authorization of the first OTC test that can detect Influenza A and B, along with SARS-CoV-2, is a major milestone in bringing greater consumer access to diagnostic tests that can be performed entirely at home. The FDA strongly supports innovation in test development, and is eager to continue advancing greater access to at-home infectious disease testing to best support public health needs.


The collective impact of COVID-19, flu and RSV underscore the importance of diagnostic tests for respiratory viruses, and the FDA recognizes the benefits that home testing can provide. The agency will continue to use its authorities to increase the number of appropriately accurate and easy-to-use at-home tests available to the public, especially tests that detect these highly contagious respiratory viruses.
