Epidemiology lays the foundation for understanding population health and building public health policy. On a broad scale, epidemiologists serve as the architects of public health initiatives. Leveraging their expertise, they analyze disease patterns and assess the health impacts on specific populations. Epidemiology highlights trends such as transmission patterns and disease prevention strategies.
Most epidemiology professionals undergo professional training to acquire the necessary skills that underscore their responsibilities. In fact, most epidemiologists need formal public health education, usually a Master of Public Health specializing in Epidemiology, to be qualified for their position. Within the framework of an MPH program, students delve into specialized coursework encompassing epidemiology and biostatistics methodologies. These include the study of directed acyclic graphs (DAG), analysis of categorical data, and observational epidemiology study design alongside foundational statistical methods such as t-tests, linear regression, and risk ratios.
