Diseases & Conditions (CDC): A-Z list of diseases, disorders and conditions. Maintained by the Centers for Disease Control and Prevention.

Health Topics (MedlinePlus)Search for a disease by browsing an A-Z list, by body system, or by broad disease type. Maintained by the National Library of Medicine.
