As the COVID-19 pandemic is working through its second year in the United States, we have seen some changes in the virus, vaccine recommendations, and advice for other measures to control infection. Since many individuals in the U.S. are now vaccinated and about 50% of those have had at least one booster, the risk of death and hospitalization has decreased over time. At the same time, variant viruses have emerged that are more easily transmitted, and many people have now had COVID-19 at least once in the course of the pandemic.

In late September, new recommendations were also provided with regard to masking and quarantine/isolation. Community levels of COVID-19 infection (which are county-specific) are to be used as a guide for mask wear. In locations where infection rates are medium to high, masking is recommended. Those exposed to COVID-19 no longer need to quarantine but instead should wear a well-fitting face mask for 10 days, watch for signs of infection, and should get tested on day 6, regardless of symptoms. Individuals who test positive or are sick with COVID-19 should stay home for at least 5 days and should use their symptoms to determine when they can end isolation. Those with minimal or no symptoms can return to work and school on day 6.
