CDC ditches 5-day COVID isolation, argues COVID is becoming flu-like

COVID-19 is becoming more like the flu and, as such, no longer requires its own virus-specific health rules, the Centers for Disease Control and Prevention said Friday alongside the release of a unified "respiratory virus guide."

In a lengthy background document, the agency laid out its rationale for consolidating COVID-19 guidance into general guidance for respiratory viruses—including influenza, RSV, adenoviruses, rhinoviruses, enteroviruses, and others, though specifically not measles. The agency also noted the guidance does not apply to health care settings and outbreak scenarios.

"COVID-19 remains an important public health threat, but it is no longer the emergency that it once was, and its health impacts increasingly resemble those of other respiratory viral illnesses, including influenza and RSV," the agency wrote.
