Outbreaks - investigation and control

The video tutorial explains what an outbreak is and how public health officials investigate and control them. It details the role of outbreak control teams, which conduct epidemiological, laboratory, and environmental investigations while implementing control measures. The process includes establishing a case definition, developing hypotheses on exposure and transmission, and using descriptive epidemiology to understand the outbreak's spread. Control measures are tailored to the outbreak and may include environmental actions, vaccination, and public education.
