Epidemiologists use a variety of methods to study diseases, including:
Descriptive Studies: These studies aim to describe the distribution of diseases and health outcomes in populations. They often involve case reports, case series, and cross-sectional studies. Analytical Studies: These studies aim to investigate the causes and risk factors of diseases. They often involve cohort studies, case-control studies, and randomized controlled trials. Experimental Studies: These studies involve the manipulation of one variable to determine its effect on another variable. They are often used to test the efficacy and safety of new treatments or interventions.
