Acute diseases: An epidemiologic perspective

Many underdeveloped countries still struggle with the public health issue of acute illnesses, especially with the emergence of injuries as a major category of acute diseases. Control of the acute disease is challenging particularly when it occurs as an outbreak, either in isolation or as part of a wider epidemic. This narrative review summarizes the definition, epidemiologic transition, pattern and modes of spread, classification, epidemiologic measures, community burden, prevention, control, and future challenges of acute disease. This review is to provide a reference for epidemiologists, clinicians, researchers, and policymakers.
