Nature of the Work

Epidemiologists investigate and describe the causes and spread of disease, and develop the means for prevention or control. Applied epidemiologists, who usually work for State health agencies, respond to disease outbreaks, determining their causes and helping to contain them. Research epidemiologists study diseases in laboratories and in the field to determine how to prevent future outbreaks.

Education and Training

Most applied epidemiologists are required to have a master's degree from a school of public health. Some research epidemiologists may need a Ph.D. or medical degree, depending on the work they perform.

Job Outlook

Employment change. Faster than average employment growth is projected for epidemiologists. A heightened awareness of bioterrorism and rare but infectious diseases, such as West Nile Virus or Avian flu, should spur demand for these workers.

Job prospects. Epidemiologists can expect excellent opportunities. Many States report shortages of qualified workers for applied epidemiology positions. There is greater competition for jobs as research epidemiologists.
