Last week the CDC updated its Covid isolation guidelines. The agency says it's "to help the public better protect themselves and understand their risk."
Most importantly, there is no longer any distinction between those who are fully vaccinated and those who are unvaccinated against the virus. Instead, the CDC says anyone can end isolation after five days if asymptomatic or if fever-free for 24 hours and other symptoms are improving. Thereafter, one should mask around others either through day 10 or sooner after two sequential negative tests 48 hours apart.
