Contact tracing involves:

Contact tracing involves:

• A. Identifying and monitoring people who may have come into contact with an infected person to stop spread
• B. A method of diagnosing infections
• C. A strategy for vaccine distribution
• D. A process of reporting adverse events

Answer: (A)

Identifying and monitoring people who may have come into contact with an infected person to stop spread is the essence of contact tracing. After a case is identified, health workers interview them to map who they may have exposed during the infectious period. Those contacts are then alerted, assessed for risk, and advised on actions such as testing, watching for symptoms, and isolating or quarantining as appropriate. The goal is to interrupt transmission by reducing opportunities for further spread. This is different from diagnosing infections (which relies on tests), vaccine distribution, or reporting adverse events, which are separate activities. Effective tracing relies on timely reporting, accurate information, and cooperation, and may be aided by digital tools while protecting privacy.
