Contact tracing is a public health practice used to identify and notify individuals who may have been in close contact with someone infected with a contagious disease. The goal of contact tracing is to prevent further transmission of the disease by quickly identifying and isolating individuals who may have been exposed. This process typically involves interviewing infected individuals to gather information about their recent contacts, then reaching out to those contacts to provide guidance on testing, monitoring symptoms, and quarantine measures. Contact tracing plays a crucial role in controlling infectious disease outbreaks and preventing the spread of illness within communities.
