What is the primary focus of epidemiology?

The primary focus of epidemiology is searching for causal relationships in health and illness. This field examines the distribution and determinants of health-related states or events in specified populations. By understanding the factors that contribute to health issues, epidemiologists can identify potential risks and develop strategies to prevent diseases and improve health outcomes.

Epidemiology encompasses much more than simply tracking the incidence of communicable diseases, as it also involves studying non-communicable diseases, environmental health, behavioral health, and the effects of health interventions. While tracking disease incidence is a critical aspect of epidemiology, it serves as just one component of a broader examination into why certain health outcomes occur, which ultimately drives public health actions and policies.

Focusing on reducing debilitating injuries in the workplace or improving access to healthcare services represents important public health goals but falls under specific domains that may utilize epidemiological data rather than embody the overall focus of the discipline itself.
