Medical encyclopedia

A medical encyclopedia is a comprehensive written compendium that holds information about diseases, medical conditions, tests, symptoms, injuries, and surgeries. It may contain an extensive gallery of medicine-related photographs and illustrations. A medical encyclopedia provides information to readers about health questions. It may also contain some information about the history of diseases, the development of medical technology uses to detect diseases in its early phase. A licensed physician should be consulted for diagnosis and treatment of any and all medical conditions.

Four major elements define a medical encyclopaedia: its subject matter, its scope, its method of organization, and its method of production:

MedlinePlus is a free Web site that provides consumer health information for patients, families, and health care providers. MedlinePlus brings together quality information from the United States National Library of Medicine, the National Institutes of Health (NIH), other U.S. government agencies, and health-related organizations. The U.S. National Library of Medicine produces and maintains MedlinePlus.

The Centers for Disease Control and Prevention (or CDC) is an agency of the United States Department of Health and Human Services based in the Metro Atlanta area, adjacent to the campus of Emory University and northeast of downtown Atlanta. It works to protect public health and safety by providing information to enhance health decisions, and it promotes health through partnerships with state health departments and other organizations. The CDC focuses national attention on developing and applying disease prevention and control (especially infectious diseases), environmental health, occupational safety and health, health promotion, prevention and education activities designed to improve the health of the people of the United States.
