Epidemic Intelligence Service

The Epidemic Intelligence Service is a specialist field epidemiology program of the Centers for Disease Control and Prevention founded in 1951. It trains health professionals in applied epidemiology and outbreak response, deploying officers to respond to public health emergencies such as infectious disease outbreaks, environmental exposures, and bioterrorism events. Alumni have moved into leadership roles at agencies including the World Health Organization, Pan American Health Organization, Food and Drug Administration, and state health departments such as the New York State Department of Health and California Department of Public Health.

History

The program was initiated by Alexander Langmuir at the Centers for Disease Control and Prevention in response to concerns arising from the Korean War era and the threat of biological warfare, and expanded amid Cold War public health priorities. Early activities intersected with investigations of poliomyelitis outbreaks linked to the Salk vaccine era and surveillance initiatives influenced by the Communicable Disease Center's evolution into the CDC. During the 1960s and 1970s, officers worked on field investigations related to smallpox eradication efforts, cholera surveillance, and responses to the 1976 swine flu outbreak at Fort Dix. In later decades, the program engaged in responses to the HIV/AIDS pandemic, the 1993 hantavirus outbreak in the Four Corners, the 2001 anthrax attacks investigations, and the 2014 West Africa Ebola epidemic. During the 21st century, EIS officers participated in responses to the 2009 H1N1 pandemic, the 2016 Zika virus epidemic in the Americas, the COVID-19 pandemic, and international outbreak support coordinated with the Global Outbreak Alert and Response Network.

EIS is administered within the Centers for Disease Control and Prevention's Center for Surveillance, Epidemiology, and Laboratory Services and works in coordination with CDC's offices such as the Office of Public Health Preparedness and Response and the National Center for Immunization and Respiratory Diseases. The program maintains affiliations with state and territorial health departments including the Texas Department of State Health Services, Florida Department of Health, and New York City Department of Health and Mental Hygiene, as well as with international partners like the World Health Organization and the Pan American Health Organization. Leadership roles have included directors who liaise with congressional committees such as the United States House Committee on Energy and Commerce and interagency partners including the Department of Health and Human Services and the Federal Emergency Management Agency.

Candidates are typically recruited from clinical backgrounds associated with institutions like Johns Hopkins University, Harvard University, University of California, San Francisco, Emory University School of Medicine, and University of Washington. Applicants often hold degrees from programs such as the National Board of Public Health Examiners-accredited schools and completion of residency programs at institutions like Mayo Clinic or Massachusetts General Hospital. Training includes mentored field assignments, didactic sessions at CDC headquarters in Atlanta, Georgia, and collaboration with academic partners such as the EIS Conference and universities participating in the Field Epidemiology Training Program. Instruction covers topics tested in examinations used by bodies like the American Board of Preventive Medicine and involves laboratory collaboration with agencies such as the Food and Drug Administration and the National Institutes of Health.

Officers conduct outbreak investigations, surveillance system evaluations, and applied research. Deployments have involved coordination with the World Health Organization during international emergencies, collaboration with the United Nations agencies on humanitarian crises, and support for military public health units such as those associated with the U.S. Army Medical Research Institute of Infectious Diseases. EIS officers serve in roles across federal entities including the Centers for Medicare & Medicaid Services-linked initiatives, support state responses for departments like the California Department of Public Health, and contribute to global health security programs funded by partners such as the Bill & Melinda Gates Foundation. Responsibilities frequently include publishing in journals such as Morbidity and Mortality Weekly Report, advising on vaccine policy with bodies like the Advisory Committee on Immunization Practices, and providing expert testimony before committees including the United States Senate Committee on Health, Education, Labor, and Pensions.

EIS officers have led historic investigations: linking contaminated water to cholera outbreaks that informed World Health Organization water safety guidance; identifying sources during salmonella and E. coli O157:H7 foodborne illness outbreaks that shaped Food Safety and Inspection Service and Food and Drug Administration policy; investigating the 1976 Legionnaires' disease outbreak that resulted in identification of Legionella pneumophila; characterizing early clusters during the HIV/AIDS epidemic that guided clinical and public health responses; and identifying the novel hantavirus in the 1993 Four Corners hantavirus outbreak. EIS contributions include methodological advances in case-control studies, field surveillance protocols adopted by the World Health Organization and the Pan American Health Organization, and leadership in vaccine safety monitoring contributing to decisions by the Advisory Committee on Immunization Practices and the Vaccine Injury Compensation Program.

The program has produced leaders who became heads of institutions such as the Centers for Disease Control and Prevention, state health departments, and international organizations like the World Health Organization regional offices. Its alumni network influences policy at agencies including the Department of Health and Human Services, Food and Drug Administration, and National Institutes of Health. Criticisms include debates over resource allocation between domestic and international deployments debated in hearings before the United States Congress, concerns about institutional emphasis reflected in CDC budget discussions with the Office of Management and Budget, and critiques in academic outlets regarding the balance between acute outbreak response and long-term public health capacity building at academic centers such as Columbia University and University of California, Berkeley.
