The US Centers for Disease Control and Prevention is expected to shift its Covid-19 isolation guidance this spring to say that people no longer need to isolate once they have been fever-free for 24 hours and their symptoms are mild or improving, according to the Washington Post.

The Post cited four unnamed agency officials and said the planned shift was discussed internally last week and in a briefing with state health officials.

Since 2021, the agency has said people should isolate for at least five days if they tested positive for Covid-19, and then continue to mask. The updated guidance would bring Covid-19 in line with guidance for other respiratory viruses, such as flu.

CNN previously reported that California and Oregon had recently broken with CDC’s guidance to say that people who test positive for Covid-19 are no longer expected to isolate for a set period of time — and those without symptoms don’t have to isolate at all.

The science around Covid-19 transmission hasn’t changed, but experts broadly agreed after the California and Oregon changes that easing isolation timeframes won’t significantly increase community transmission or severe outcomes — in part because the virus has been circulating at very high levels, even with more restrictive guidance in place.
