Mission, Role and Pledge


Equitably protecting health, safety & security.

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.


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.

Pledge to the American People
  1. Be a diligent steward of the funds entrusted to our agency
  2. Provide an environment for intellectual and personal growth and integrity
  3. Base all public health decisions on the highest quality scientific data that is derived openly and objectively
  4. Place the benefits to society above the benefits to our institution
  5. Treat all persons with dignity, honesty, and respect
