The vision for health security described in the National Health Security Strategy (NHSS) is built on a foundation of community resilience: the sustained ability of communities to withstand and recover from adversity. Resilient communities include healthy individuals, families, and communities with access to health care, both physical and psychological, and with the knowledge and resources to know what to do to care for themselves and others in both routine and emergency situations. Enhanced resilience is considered critical to mitigating vulnerabilities, reducing negative health consequences, and rapidly restoring community functioning. ABC works to promote strategies for building individual and community resilience that are inclusive of both behavioral health and the functional needs of at-risk individuals. Such strategies will improve communities’ ability to maximize resources, meet needs, and recover from the adverse health consequences of public health emergencies and disasters at the individual and community levels.
