What does an epidemiologist actually do when a disease outbreak occurs?
An epidemiologist calculates rates of disease and follows set steps to investigate an outbreak in a population.
Epidemiology here is the population side of the field, so the work is about groups of people rather than one patient. The Centers for Disease Control and Prevention teaches it as a course in which learners calculate different rates of disease and go through the steps an epidemiologist takes to investigate a disease outbreak. The concepts grouped on this page, such as attack rate, incidence and prevalence, are the measures used to describe how often a disease occurs and how it spreads.
