Our mission

CDC works 24/7 to protect America from health, safety and security threats, both foreign and in the U.S. Whether diseases start at home or abroad, are chronic or acute, curable or preventable, human error or deliberate attack, CDC fights disease and supports communities and citizens to do the same.

CDC increases the health security of our nation. As the nation's health protection agency, CDC saves lives and protects people from health threats. To accomplish our mission, CDC conducts critical science and provides health information that protects our nation against expensive and dangerous health threats and responds when these arise.


The 2022-2027 CDC Strategic Plan advances science and health equity and affirms the agency's commitment to one unified vision— equitably protecting health, safety, and security. The plan continues to leverage 5 core capabilities of the agency, reflecting our commitment to equity and diversity and lifting up where we have invested through the COVID-19 pandemic. Our work is underscored by the agency's Pledge to the American People and dedication to use timely data and science to drive and communicate customer-centered, high-impact public health action.

CDC Moving Forward‎

In April 2022, CDC launched an effort to refine and modernize its structures, systems, and processes around developing and deploying our science and programs. The goal was to learn how to pivot our long-standing practices and adapt to pandemics and other public health emergencies, then to apply those lessons across the organization. The effort included a review of key workflows, with a particular focus on ensuring CDC's science reaches the public in an understandable, accessible, and implementable manner as quickly as possible.
