NCID Website Has Been Retired

The National Center for Infectious Diseases (NCID) has been officially reorganized: its former divisions and programs have been realigned into multiple national centers. As a result, the website of the former NCID has been retired.

For infectious disease health topic information, please consult the CDC Diseases and Conditions A-Z Index.

For information about the new centers, please visit their CDC websites:

Portions of the old NCID website are being kept online temporarily for purely archival purposes. Visit the temporary index page of archived pages.
