What is the purpose of "contact tracing"?

Contact tracing is a crucial epidemiological tool used to identify and reach out to individuals who have been exposed to an infectious disease. The main objective is to interrupt the transmission of the disease by informing these individuals about their potential exposure so they can take necessary precautions, such as self-quarantine or seeking medical advice. This proactive step helps to limit further spread of the disease within the community.

In the context of infectious disease outbreaks, such as during the COVID-19 pandemic, effective contact tracing allowed health authorities to quickly isolate cases and notify close contacts about their risk status. This leads to better management of outbreaks and protects public health.

While locating healthcare resources, tracking recovery of infected individuals, and monitoring public health policies are important aspects in the fight against diseases, they do not capture the essence of what contact tracing specifically entails, which is the direct communication and prevention strategy aimed at those who may have come into close contact with a confirmed case of an infectious disease.
