Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems. Epidemiologists investigate the patterns of disease, injury, and other health conditions in human populations. They seek to understand how these conditions spread, what factors contribute to their occurrence, and how to prevent or manage them. This field employs scientific methods to collect and analyze data, allowing for the identification of trends, risk factors, and the effectiveness of interventions. Key concepts in epidemiology include incidence, prevalence, mortality, and morbidity. Epidemiologists work in a variety of settings, including public health agencies, research institutions, hospitals, and government organizations. Their work is crucial for public health policy, disease surveillance, outbreak investigations, and the development of strategies to improve population health and well-being. By understanding the 'when', 'where', and 'why' of health events, epidemiology provides the evidence base for public health action.
