Summary of Guidance to Minimize the Impact of COVID-19 on Individuals, Communities, and Healthcare Systems – United States, August 2022

COVID-19 Prevention Strategies

Monitor COVID-19 community levels to guide COVID-19 prevention efforts. People can use information about the current level of COVID-19 impact on their communities to decide which preventive behaviors to use and when (at any time or at a specific time), based on their own and family members’ risk of serious illness, their risk tolerance and settings specific factors. CDC’s COVID-19 Community Level reflects the current impact of COVID-19 on the community and identifies geographic periods during which an increase in severe COVID-19-related outcomes is likely based on previous hospitalization rates, bed occupancy rates, and COVID-19 incidence rates *** (1). The clear goal of community-level prevention recommendations for COVID-19 is to reduce medically significant illness and limit stress on the healthcare system. At all COVID-19 community levels (low, moderate, and high), recommendations emphasize timely vaccination, improved ventilation, testing of symptomatic and exposed individuals, and isolation of infected individuals. At the moderate COVID-19 community level, recommended strategies include adding protective measures (eg, use of masks or respirators that provide a higher level of wearer protection) for those at high risk for severe illness. At the high COVID-19 community level, other recommendations focus on all people wearing masks indoors in public and further strengthen protections for high-risk groups.††† As SARS-CoV-2 continues to spread, changes at the community level of COVID-19 in jurisdictions can help indicate when certain prevention strategies or social contact should be discontinued or increased based on the level of risk of severe illness to individuals or their families. The COVID-19 community level provides a broad framework for public health officials and jurisdictions to assess the need for public health interventions by incorporating local information, using and adapting to local circumstances.

nonpharmacological interventions. Implementing multiple prevention strategies can help protect individuals and communities from SARS-CoV-2 exposure and reduce the risk of medically significant illness and death by reducing the risk of infection (Table). Implementation of multiple nonpharmacological preventive interventions can complement the use of vaccines and therapies, especially as the community level of COVID-19 increases and in populations at high risk for severe illness. The CDC’s COVID-19 prevention recommendations no longer differentiate based on a person’s vaccination status because breakthrough infections occur, although they are usually mild (16(17). In addition to the strategies recommended at all COVID-19 community levels, education and information delivery to help individuals understand their risk of significant medical illness complements the recommendations for risk-based prevention strategies.

Detect current infection. Diagnostic tests can detect infection early so that infected people can take action to reduce the risk of spreading the virus and receive treatment when clinically indicated to reduce the risk of serious illness and death. All people should seek active infection testing if they develop symptoms or have known or suspected exposure to someone with COVID-19. When considering whether and where to screen and test asymptomatic individuals with no known contacts, public health officials may consider prioritizing high-risk congregate settings, such as long-term care facilities, homeless shelters, and penitentiaries. Teaching facilities, as well as workplaces that include congregations. Housing with limited access to health care.§§§ In these types of high-risk cluster settings, screening testing may complement diagnostic testing of symptomatic individuals by identifying asymptomatic infected individuals.18,19). When implemented, screening testing strategies should include everyone regardless of vaccination status. Screening tests may not be cost-effective in general community settings, especially when COVID-19 prevalence is low (20,twenty one).

isolation. Symptomatic or infected people should be quarantined in time, infected people should be quarantined for ≥5 days, and must wear a well-fitting, high-quality mask or respirator when they are around others. Infected individuals can end their isolation after 5 days, and they should continue to wear a mask or respirator around others at home and in public only if they are not on medication and have no fever for ≥24 hours and all other symptoms have improved.Day 10¶¶¶ (number) (twenty two,twenty three). People who can have an antigen test and choose to use the test to determine when they can stop wearing a mask should wait until at least the 6th day for their first test, and they have no fever for ≥24 hours and all other symptoms without fever reducers has been improved. Due to improved detection sensitivity, using an antigen test with an interval of ≥48 hours between tests provides more reliable information (twenty four). Two consecutive negative test results are required to stop wearing a mask. If either test comes back positive, people should continue to wear masks around other people and continue testing every 48 hours until two consecutive negative results. ****

Manage SARS-CoV-2 exposure. The CDC now recommends case investigation and contact tracing only in health care facilities and certain high-risk gathering places.†††† In all other cases, public health efforts can focus on case notification and providing contacts with information and resources about obtaining testing. People who have recently confirmed or suspected exposure to an infected person should wear a mask around other people for 10 days when indoors in public and should be tested ≥5 days after exposure (or earlier if symptomatic) regardless of their vaccine What is the status of vaccination.§§§§ Given the high prevalence of anti-SARS-CoV-2 seroprevalence in the population (7,16), and to limit the social and economic impact, quarantine of contacts is no longer recommended regardless of vaccination status.
