Epidemiology and Reasoning for Medical Students

Epidemiology is the branch of medicine that deals with the incidence, prevalence, distribution, and determinants of health related states or events. It also plays a role in the possible control of health related events such as disease outbreaks or environmental exposures. Epidemiologists use many tools to study diseases and the health of populations.
