What is the study of how disease is distributed in populations and the factors that influence distribution?

Explanation:
Epidemiology focuses on how diseases are distributed in populations and the factors that influence that distribution. It looks at rates like incidence and prevalence and examines patterns by who is affected, where, and when, while also seeking the determinants that explain those patterns—genetic, environmental, behavioral, social, and economic influences. This understanding guides public health actions, from prevention strategies to outbreak investigations and resource allocation. This field differs from pharmacology (drug actions), immunology (immune responses), and pathology (tissue-level disease processes).
