Oregon health officials suggest that people with Covid stay home until they’ve gone 24 hours without a fever and are feeling better, rather than the CDC’s five-day isolation recommendation. While Covid is still present, trends in Covid-related hospitalizations and wastewater surveillance in Oregon show improvement and high immunity levels. The current recommendation to isolate for five days may not be entirely evidence-based, as some experts say it was put in place to prevent societal disruption during the first Omicron wave. However, experts still believe that people with Covid are likely contagious for at least five days, and ending isolation earlier may not be biologically sound.
