Health systems refer to the organizations, institutions, resources, and people whose primary purpose is to improve health. They encompass a wide range of activities, from providing clinical services to public health initiatives, and are critical in the context of Epidemiology.
Health systems play a crucial role in disease surveillance, prevention, and control. They ensure the collection, analysis, and dissemination of health data necessary for identifying health trends and emerging threats. Effective health systems facilitate interventions that reduce the spread of diseases and improve population health.
