Abstract
Public health care practitioners and organizations are a part of community readiness for, response to, and recovery from emergencies and disasters of all kinds. Although response to health threats, particularly communicable disease outbreaks, have long been a part of public health practice, 2 advancements in preparedness, including the integration of public health into the broader community emergency response system and the clarification of exactly what knowledge, skills, and attitudes a public health professional brings to the response, have been made since 2001. This article presents the newly affirmed core competencies to be attained and maintained by the majority of the public health workforce and discusses some of the many ways in which these competencies influence practice, research, and education.
