Abstract
In the 10 months since the first confirmed case of coronavirus disease 2019 (COVID-19) was reported in the United States on January 20, 2020 (1), approximately 13.8 million cases and 272,525 deaths have been reported in the United States. On October 30, the number of new cases reported in the United States in a single day exceeded 100,000 for the first time, and by December 2 had reached a daily high of 196,227.* With colder weather, more time spent indoors, the ongoing U.S. holiday season, and silent spread of disease, with approximately 50% of transmission from asymptomatic persons (2), the United States has entered a phase of high-level transmission where a multipronged approach to implementing all evidence-based public health strategies at both the individual and community levels is essential. This summary guidance highlights critical evidence-based CDC recommendations and sustainable strategies to reduce COVID-19 transmission. These strategies include 1) universal face mask use, 2) maintaining physical distance from other persons and limiting in-person contacts, 3) avoiding nonessential indoor spaces and crowded outdoor spaces, 4) increasing testing to rapidly identify and isolate infected persons, 5) promptly identifying, quarantining, and testing close contacts of persons with known COVID-19, 6) safeguarding persons most at risk for severe illness or death from infection with SARS-CoV-2, the virus that causes COVID-19, 7) protecting essential workers with provision of adequate personal protective equipment and safe work practices, 8) postponing travel, 9) increasing room air ventilation and enhancing hand hygiene and environmental disinfection, and 10) achieving widespread availability and high community coverage with effective COVID-19 vaccines. In combination, these strategies can reduce SARS-CoV-2 transmission, long-term sequelae or disability, and death, and mitigate the pandemic's economic impact. Consistent implementation of these strategies improves health equity, preserves health care capacity, maintains the function of essential businesses, and supports the availability of in-person instruction for kindergarten through grade 12 schools and preschool. Individual persons, households, and communities should take these actions now to reduce SARS-CoV-2 transmission from its current high level. These actions will provide a bridge to a future with wide availability and high community coverage of effective vaccines, when safe return to more everyday activities in a range of settings will be possible.Entities:

Individual- and community-level public health strategies to reduce SARS-CoV-2 transmission*
| Recommended public health strategies | Individual- and household-level strategies | Community-level strategies (at state or local level) | Links to guidance |
|---|---|---|---|
| Universal use of face masks | Consistent and correct use of face masks, including within the household if there is a COVID-19 case or a person with a known or possible exposure in the household | Issue policies or directives mandating universal use of face masks in indoor (nonhousehold) settings | Considerations for wearing masks: |
| Plan for provision of face masks for specific populations if needed | Caring for someone sick at home, when to wear a mask or gloves: | ||
| Protect your home: | |||
| Physical distancing and limiting contacts | Maintain physical distance (≥6 feet) from other persons when possible, and limit number of contacts with persons outside the immediate household | Physical barriers and visual reminders might promote adherence to maintaining physical distance | Social distancing: |
| Personal and social activities: | |||
| Avoid nonessential indoor spaces and crowded outdoor settings | Avoid nonessential indoor spaces and crowded outdoor settings | Issue policies or directives restricting some nonessential indoor spaces that pose the highest risk for transmission | Daily activities and going out: |
| Promoting flexible worksites (e.g., telework); apply limits to occupancy of indoor spaces and to the size of social gatherings | Considerations for events and gatherings: | ||
| Increased testing, diagnosis, and isolation | Persons with a known exposure to someone with COVID-19, with possible exposure, or who experience symptoms should promptly seek testing; symptomatic or infected persons should isolate promptly; exposed persons should quarantine | Increase access to testing, including expanded screening testing of prioritized persons/groups, prioritizing those with many interactions (or interactions with persons at high risk) based on their occupational or residential setting | Testing: |
| Expanded screening testing: | |||
| Promptly report test results to the person tested and to public health authorities | Isolate if you are sick: | ||
| Guidance for health departments about COVID-19 testing in the community: | |||
| Prompt case investigation and contact tracing to identify, quarantine, and test close contacts | Persons with diagnosed COVID-19 should provide names of known contacts; close contacts should anticipate a call from the health department, answer the call, adhere to quarantine, seek testing, and encourage their household members to quarantine | When incidence is high and overwhelms capacity, prioritize case investigation and contact tracing to promptly quarantine and test close contacts, based on time since sample collection and risk for spread to others (e.g., those working in high-density settings) | When to quarantine: |
| Contact tracing (your health): | |||
| Contact tracing (health departments): | |||
| Prioritizing case investigation and contact tracing: | |||
| Quarantine: | |||
| Safeguarding persons most at risk for severe illness or death | Persons with underlying medical conditions or risk factors that place them at increased risk for severe illness or death should minimize contact with nonhousehold members and nonessential indoor spaces | Protect persons most at risk for severe illness or death through 1) identifying populations at high risk in the community and 2) expanding access to testing, provision of support services, and messaging | People at increased risk: |
| Protecting essential workers | Essential workers should employ all available public health strategies to reduce their risk (e.g., wear face masks and keep physical distance) | Protect essential workers through policies directing administrative and structural prevention as well as expanded testing | Essential services and critical infrastructure: |
| COVID-19 critical infrastructure sector response planning: | |||
| CISA guidance on the essential critical infrastructure workforce: | |||
| Postponing travel | Travel should be postponed. Those who choose to travel internationally should be tested with a viral test 1–3 days before departure and retested 3–5 days after arrival; domestic travelers should also consider getting tested | Issue policies or directives mandating universal use of face masks on all modes of public transportation | Travel: |
| Travelers should stay home or reduce nonessential activities before and after travel and be diligent about mask wearing, physical distancing, hand hygiene, and symptom monitoring | When not to travel: | ||
| Wear face masks on public transportation conveyances and at transportation hubs: | |||
| Mask and travel guidance: | |||
| Domestic travel: | |||
| Testing and international air travel: | |||
| Increased room air ventilation, enhanced hand hygiene, and cleaning and disinfection | Increase room air ventilation | Enhance ventilation and cleaning and disinfection, particularly of essential indoor spaces | SARS-CoV-2 and potential airborne transmission: |
| Frequent handwashing | Ensure provision of adequate hand sanitation supplies | Ventilation: | |
| When and how to wash your hands: | |||
| Cleaning and disinfecting: | |||
| Widespread availability and coverage with effective vaccines | Seek vaccine when appropriate following ACIP recommendations | Plan for distribution and administration of vaccines to achieve high community coverage | Vaccines: |
| Continue to follow all mitigation measures until community vaccination coverage is adequate | Communicate that mitigation measures still need to be followed until community vaccination coverage is determined to be adequate | Vaccination planning: |
