CDC ditches 5-day COVID isolation, argues COVID is becoming flu-like
The agency released a unified “practical” guidance for respiratory viruses.

"Reported deaths involving COVID-19 are several-fold greater than those reported to involve influenza and RSV. However, influenza and likely RSV are often underreported as causes of death," the CDC said. In the 2022–2023 respiratory virus season, there were nearly 90,000 reported COVID-19 deaths. For flu, there were 9,559 reported deaths, but the CDC estimates the true number to be between 18,000 and 97,000. In the current season, there have been 32,949 reported COVID-19 deaths to date and 5,854 reported flu deaths, but the agency estimates the real flu deaths are between 17,000 and 50,000.
"Total COVID-19 deaths, accounting for underreporting, are likely to be higher than, but of the same order of magnitude as, total influenza deaths," the agency concluded.
In all, the CDC was ready to fold SARS-CoV-2 into the gang of common seasonal respiratory viruses, with most cases mild and undiagnosed. "Viruses cause most acute respiratory illnesses, but it is rarely possible to determine the type of virus without testing, and oftentimes testing does not change clinical management," the agency wrote.
