Epidemiology is the study of the distribution and determinants of health-related states and events in defined populations, and the application of that knowledge to prevent and control disease. It quantifies who is affected, where, and when, and identifies the risk factors, exposures, and causal pathways that explain patterns of illness. Core methods include surveillance, prevalence and incidence measurement, retrospective and cross-sectional analysis, cohort and case studies, and the investigation of outbreaks and temporal trends. The discipline underpins public health and evidence-based medicine by informing screening, prevention programmes, and policy. Research in this field examines the distribution and histopathological patterns of thyroid disease, the epidemiology and management of seasonal influenza outbreaks in long-term care, temporal trends in syphilis and associated infections, malaria and typhoid coinfection, the role of human papillomavirus in carcinogenesis, vector and parasitic infections of public health importance, colorectal cancer screening programme development, and the prevalence of neurological and sleep disorders. Both communicable and non-communicable conditions, and zoonotic and veterinary aspects, fall within its scope. By measuring disease frequency and identifying determinants, epidemiology guides the targeting of interventions, the evaluation of their impact, and the equitable allocation of health resources, making it a foundational science for protecting and improving population health.
