In outbreak control, rapid outbreak immunization serves primarily to:

• A. To treat infected individuals
• B. Quickly immunize populations at risk during an outbreak
• C. To detect virus via lab tests
• D. To remove infected individuals from community

Answer: (B)

Rapid outbreak immunization focuses on quickly creating immunity in people who could be infected, to stop transmission. By immunizing at‑risk populations as soon as an outbreak is detected, the number of susceptible individuals drops rapidly, breaking transmission chains and helping the outbreak end sooner. Vaccines don’t treat people who are already infected, and this approach isn’t about detecting the virus or removing infected individuals from the community. Instead, it’s a preventive, reactive measure designed to curb spread by boosting herd immunity quickly when and where it’s needed.
