Epidemiology Hero


Epidemiology is the study of the incidence, distribution and control of disease in a population. THD epidemiologists work to prevent the spread of diseases by identifying their causes and risk factors. Their efforts provide the foundation for developing public policy and regulations regarding disease prevention.
