A-Z FAQ

What is the A-Z Index?

The CDC A-Z Index is a navigational and informational tool that makes the CDC.gov Web site easier to use. It helps you quickly find and retrieve specific information. The A-Z index is structured so that synonyms, acronyms, and cross-referencing provide multiple ways for you to access the topics and features on CDC.gov. The index includes common and scientific terms to meet the needs of consumers as well as health professionals.

What items are included?

The CDC A-Z Index lists topics with relevance to a broad cross-section of CDC.gov’s audiences. The items are representative of popular topics, frequent inquiries, or have critical importance to CDC’s public health mission. The index will continue to evolve as additional topics are added.

Why is there more than one A-Z Index?

The Diseases and Conditions A-Z index is a subset of the main A-Z list. This secondary list was created to make it easier to find information within a large, popular category. A number of sites within the CDC family of Web sites already have their own self-contained A-Z Indices. In the future, we expect to integrate these indices and develop additional sub-level indices for different components of the CDC family of Web sites.

How do I find CDC organization and program sites?

CDC organization information is available from CDC Organization. Program information can be accessed from the different organization sites, or via CDC's search engine.
