The impact of SARS-CoV-2, the virus that causes COVID-19, has changed dramatically since 2020. Although COVID-19 remains common, when compared to 2020, individual infections are less likely to result in severe illness for most people in the United States. COVID-19 poses the highest risk for older adults, infants, and people with pre-existing medical conditions, and there are multiple ways people and communities can help reduce their risk of infection.

In March 2024 CDC released updated recommendations for how people can protect themselves and their communities from respiratory viruses, including COVID-19. The new guidance brings a unified approach to addressing risks from a range of common respiratory viral illnesses, such as COVID-19, flu, and RSV, which can cause significant health impacts and strain on hospitals and health care workers. CDC is making updates to the recommendations now because the U.S. is seeing far fewer hospitalizations and deaths associated with COVID-19 and because we have more tools than ever to combat flu, COVID, and RSV.
