Which term describes collective action for the common good aimed at aiding individuals infected or exposed to infectious agents while protecting others from inadvertent exposure?

• A. Quarantine
• B. Isolation
• C. Containment
• D. Surveillance

Answer: (A)

The idea being tested is how public health protects the community by acting now to prevent potential spread while also supporting those who might be affected. Quarantine is the public health practice of restricting the movement of people who may have been exposed to an infectious agent, so they can be monitored and protected from inadvertently spreading illness to others. This approach aims to help individuals who might become ill and, at the same time, shield the broader population from exposure. It embodies collective action for the common good by balancing care for those who could be exposed with measures that prevent transmission. In contrast, isolation targets those who are known to be infected, surveillance is about monitoring disease patterns rather than restricting movement, and containment is a broader set of strategies that includes multiple measures beyond quarantining exposed individuals.
