Epidemic Intelligence Service - CDC's EIS Officer Program

Epidemic Intelligence Service

Run by the Centers for Disease Control and Prevention (CDC), the Epidemic Intelligence Service (EIS) is a unique two-year, post-graduate program of service and on-the-job training for health professionals interested in the practice of epidemiology.

Every year, CDC's EIS Program selects 70 to 80 individuals from among the nation's top health professionals to enter the program and pursue on-the-job training in applied epidemiologic skills.

EIS Opportunities at Tri-County Health
Tri-County Health Department (TCHD) is Colorado’s largest local health department, serving over 1.2 million residents in Adams, Arapahoe and Douglas Counties in metropolitan Denver.

The agency currently employs three former EIS officers.

This particular EIS position is unique in that it offers exposure to a wide variety of public health topics, depending on the EIS Officer’s interests. These areas include outbreak investigations, emergency preparedness, environmental/occupational health-related assessments, immunizations, maternal/child health, and chronic disease prevention.

She also led the agency’s intake, surveillance and assessment activities related to Hurricane Katrina evacuees. Her work as an EIS officer and supervisor has led to nine peer-reviewed articles as an author or co-author and MMWR articles.

After her EIS appointment, Dr. Ghosh decided to stay with Tri-County Health Department, and now acts as a secondary supervisor to the current EIS Officer.
