What Is the CDC and What Information Does cdc.gov Provide?

Updated

cdc.gov is the official website of the U.S. Centers for Disease Control and Prevention (CDC), a federal public health agency. It serves as a public health information portal covering diseases and conditions, healthy living, workplace safety, environmental health, injury and violence, global health, and travelers' health. Use it when you need authoritative U.S. public health guidance, disease situation updates, or access to CDC's scientific publications.

What the CDC Is

The CDC is the United States' national public health agency. Its website translates public health science into practical guidance for broad audiences, presenting scientific language in understandable form and standardizing guideline development across the agency. The site is organized for both public readers and health professionals.

Main Content Areas

The site's A to Z index is the broadest entry point. According to the site, it covers:

  • Diseases and conditions
  • Healthy living
  • Workplace safety
  • Environmental health
  • Injury, violence, and safety
  • Global health
  • Travelers' health

The Featured Topics section highlights current priorities. Examples visible on the homepage include ways to prevent measles, getting tested for HIV, type 1 diabetes, the current H5 bird flu situation, controlling asthma, and the "Learn the Signs. Act Early." developmental milestone campaign.

News and Situation Updates

The News section carries agency announcements and data releases. Recent examples include:

  • An annual report to the nation on progress against lung cancer driving down cancer mortality
  • CDC data showing encouraging progress in youth health
  • A statement on increases in recent animal rabies activity and associated human exposures
  • Lessons from the World Trade Center Health Program, 25 years after 9/11
  • A new overdose prevention data channel

Outbreak and situation pages, such as the Ebola situation summary linked from the homepage, provide current status information on specific public health events.

Scientific Journals

For researchers and health professionals, cdc.gov hosts three peer-reviewed or scientific publications:

Journal Frequency Focus
MMWR (Morbidity and Mortality Weekly Report) Weekly Timely, reliable, objective epidemiological digest
EID (Emerging Infectious Diseases) Monthly Peer-reviewed infectious disease prevention, control, and elimination
PCD (Preventing Chronic Disease) — Peer-reviewed research, public health findings, innovations, and practices on chronic diseases

How to Use the Site

  1. Start with the A to Z index if you know the topic — it links directly to disease, condition, and safety pages.
  2. Check Featured Topics for current public health priorities and situation updates.
  3. Read News for agency announcements and newly released data.
  4. Use the journals when you need primary epidemiological or peer-reviewed material rather than consumer guidance.

The site is in English (en-us). No pricing or login requirements are indicated in the available site information, so access conditions for specific pages or data tools should be confirmed on those pages directly.
