Epidemiologists (AKA “Epis” pronounced eh-pee)

Epidemiologists:

• search for the cause of disease, asking questions like: Who is sick? What are their symptoms? When did they get sick? Where could they have been exposed?
• study answers to those questions using statistical analysis to: identify people who are at risk, determine how to control or stop the spread or prevent it from happening again.
• are like disease detectives. They study data to understand the cause of disease and to determine the best strategy for controlling it or stopping it from spreading. They typically have medical backgrounds as physicians, veterinarians, scientists, and other health professionals.

Contact Tracers

• Contact tracers notify contacts that they have been exposed to a disease
• They can be epidemiologists, or a separate team
• With COVID, many public health departments have hired separate teams just to do contact tracing in order to keep up with the large volume.
