Epidemic Intelligence Service Officer Outbreak Investigations

Outbreak investigations result from requests for epidemiological assistance within the United States and throughout the world. Requests to assist with emergency responses, investigate infectious and environmental disease outbreaks, and quantify impact of diseases are examples of these responses. Sometimes these requests come in the form of an “Epi-Aid,” which is a mechanism CDC uses for public health authorities to request short-term epidemiologic assistance.

Our global investigations are conducted in collaboration with international partners, such as ministries of health and the World Health Organization, as well as CDC’s Global Health Protection and Security program.

The investigations below were conducted by the Waterborne Disease Prevention Branch’s Epidemic Intelligence Service Officers. The investigations that resulted from an official Epi-Aid request include the Epi-Aid number—the way all Epi-Aids are tracked by CDC. When available, investigations also include articles and information published in the Morbidity and Mortality Weekly Report (MMWR) and on CDC web pages.
