When a novel virus with pandemic potential emerges, nonpharmaceutical interventions, which will be called
community mitigation strategies in this document, often are the most readily available interventions to help slow
transmission of the virus in communities. Community mitigation is a set of actions that persons and communities
can take to help slow the spread of respiratory virus infections.
Community mitigation is especially important before a vaccine or drug becomes widely available.
The following is a framework for actions which local and state health departments can recommend in their community to
both prepare for and mitigate community transmission of COVID-19 in the United States. Selection and implementation
of these actions should be guided by the local characteristics of disease transmission, demographics, and public health and
healthcare system capacity.
Goals
The goals for using mitigation strategies in communities with local COVID-19 transmission are to slow the transmission of
disease and in particular to protect:
• Individuals at increased risk for severe illness, including older adults and persons of any age with underlying health
conditions (See Appendix A)
• The healthcare and critical infrastructure workforces These approaches are used to minimize morbidity and mortality
and the social and economic impacts of COVID-19. Individuals, communities, businesses, and healthcare organizations are
all part of a community mitigation strategy. These strategies should be implemented to prepare for and when there is
evidence of community transmission. Signals of ongoing community transmission may include detection of confirmed
cases of COVID-19 with no epidemiologic link to travelers or known cases, or more than three generations of transmission.
Implementation is based on:
• Emphasizing individual responsibility for implementing recommended personal-level actions
• Empowering businesses, schools, and community organizations to implement recommended actions,
particularly in ways that protect persons at increased risk of severe illness
• Focusing on settings that provide critical infrastructure or services to individuals at increased risk of severe illness
• Minimizing disruptions to daily life to the extent possible Guiding principles
• Each community is unique, and appropriate mitigation strategies will vary based on the level of community
transmission, characteristics of the community and their populations, and the local capacity to implement strategies
• Consider all aspects of a community that might be impacted, including populations most vulnerable to severe illness and
those that may be more impacted socially or economically, and select appropriate actions.
• Mitigation strategies can be scaled up or down depending on the evolving local situation.
• When developing mitigation plans, communities should identify ways to ensure the safety and social well-being
of groups that may be especially impacted by mitigation strategies, including individuals at increased risk for severe illness.
• Activation of community emergency plans is critical for the implementation of mitigation strategies. These plans may
provide additional authorities and coordination needed for interventions to be implemented.
• Activities in Table 2 may be implemented at any time regardless of the level of community transmission based on
guidance on from local and state health officials.
• The level of activities implemented may vary across the settings described in Table 2 (e.g., they may be at a minimal/
moderate level for one setting and at a substantial level for another set in order to meet community response needs).
• Depending on the level of community spread, local and state public health departments may need to implement mitigation
strategies for public health functions to identify cases and conduct contact tracing . When applied, community
mitigation efforts may help facilitate public health activities like contact tracing
