According to the CDC as of December 27, 2021 “People with COVID-19 should isolate for 5 days and if they are asymptomatic or their symptoms are resolving (without fever for 24 hours,) follow that by 5 days of wearing a mask when around others to minimize the risk of infecting people they encounter.” with it potentially changing due to omicron with the current recommendation taking the boosters and the vaccines to gain more effective protection against it. For unvaccinated people, the quarantine remains 5 days with another 5 days of strict mask use and social distancing. As of January 11, 2022, in Utah, there have been 24,000 new cases of coronavirus and a peak of 1 million daily cases across the country possibly foreshadowing another CDC guideline change to prevent more infection.
