CDC Epidemic Intelligence Service

The Epidemic Intelligence Service is a two-year postgraduate program established in 1951 to produce field epidemiologists who respond to outbreaks and public health emergencies. Staffed by officers placed throughout United States Public Health Service Commissioned Corps, Centers for Disease Control and Prevention, and collaborating agencies, the program has shaped responses to events including the Polio vaccine era, the HIV/AIDS epidemic, and the COVID-19 pandemic. Graduates have moved into leadership roles at institutions such as the World Health Organization, Pan American Health Organization, and national public health agencies including Public Health England and the Robert Koch Institute.

History

The program was founded in 1951 by Alexander Langmuir within the Communicable Disease Center to counter biological threats during the Korean War and to address outbreaks such as smallpox and diphtheria, drawing on experience from investigators involved in the 1947 smallpox outbreak in New York City. Early EIS officers worked alongside figures like Thomas Francis Jr. and Wade Hampton Frost and collaborated with state health departments including the New York City Department of Health and the Maryland Department of Health. During the 1960s and 1970s, EIS responded to events linked to the Polio vaccine controversy, investigations connected to Legionnaires' disease, and fieldwork during the Haiti cholera outbreak, interacting with researchers from the National Institutes of Health and the Johns Hopkins Bloomberg School of Public Health. In later decades, EIS played central roles in responses to the Ebola virus epidemic in West Africa, the Zika virus epidemic, and the H1N1 influenza pandemic, coordinating with global partners such as Médecins Sans Frontières, Centers for Disease Control and Prevention Foundation, and the Global Outbreak Alert and Response Network.

EIS's mission is to detect, investigate, and contain public health threats by deploying officers to outbreaks, surveillance projects, and emergency responses for pathogens like Ebola virus, Zika virus, and novel influenzas such as H5N1 influenza. Officers support surveillance systems including the National Notifiable Diseases Surveillance System, contribute to policy at agencies like the Food and Drug Administration and the Department of Health and Human Services, and advise international partners including the World Health Organization and the Pan American Health Organization. The unit functions as an operational arm for applied epidemiology, collaborating with institutions such as the Council of State and Territorial Epidemiologists, the American Public Health Association, and academic centers like the Harvard T.H. Chan School of Public Health.

Recruitment targets clinicians, epidemiologists, and laboratorians holding degrees from institutions including Harvard University, Yale University, Columbia University, and the University of California, Berkeley. Applicants often have experience at state agencies such as the California Department of Public Health or international organizations like Doctors Without Borders and undergo selection coordinated with the United States Public Health Service Commissioned Corps. The two-year training includes outbreak investigations with mentors drawn from Alexander Langmuir's lineage, coursework at universities such as the Emory University Rollins School of Public Health, and field deployments alongside partners like the Federal Emergency Management Agency and the National Institutes of Health. Trainees present findings at venues including the International Conference on Emerging Infectious Diseases and publish in journals associated with the American Medical Association and the New England Journal of Medicine.

EIS officers investigated pivotal events including the original surveillance of polio in the 1950s, early recognition of the AIDS epidemic in the 1980s in collaboration with clinicians at San Francisco General Hospital, outbreak control during the Legionnaires' disease investigation with the Centers for Disease Control and Prevention Laboratory Science, and contact tracing in the Ebola virus epidemic in West Africa with partners such as MSF. The service contributed to vaccine safety surveillance during the 1976 swine flu outbreak and the development of field methods used in responses to the H1N1 influenza pandemic and the COVID-19 pandemic, coordinating with agencies like the Food and Drug Administration and research centers including the Wright-Patterson Air Force Base laboratories. EIS alumni have authored landmark studies at institutions including the Johns Hopkins University, the University of Oxford, and the London School of Hygiene & Tropical Medicine.

EIS officers are commissioned, often entering the United States Public Health Service Commissioned Corps, and are assigned to posts within the Centers for Disease Control and Prevention, state health departments such as the Florida Department of Health, and international postings with the World Health Organization and the Pan American Health Organization. Career trajectories lead to roles at academic centers including the Johns Hopkins Bloomberg School of Public Health, policy positions at the Department of Health and Human Services, leadership in agencies like the National Institutes of Health, and global health posts at organizations such as United Nations Children's Fund and World Bank. Notable alumni have become directors and scholars at institutions such as the Emory University School of Medicine and contributors to public health law initiatives at the Centers for Medicare & Medicaid Services.

EIS has faced critique over issues including deployment policies during the HIV/AIDS epidemic and allegations of inadequate representation from marginalized regions, prompting debate with organizations like the American Civil Liberties Union and academic critics at the University of California, Los Angeles. Controversies have arisen around data transparency during incidents like the 2001 anthrax attacks and scrutiny regarding resource allocation in responses to outbreaks such as the Ebola virus epidemic in West Africa, drawing attention from media outlets including The New York Times and public interest groups such as Human Rights Watch. Reforms have been discussed with stakeholders including the Council of State and Territorial Epidemiologists and legislative bodies such as the United States Congress to address diversity, deployment ethics, and interagency coordination.
