Which of the following was NOT listed among major CDC field activities in Liberia?

• A. Advisory Incident Management structure and function
• B. Data management
• C. Vaccination campaigns
• D. Infection control

Answer: (C)

The main idea is recognizing which activities are typically at the center of on-the-ground outbreak response operations. In Liberia, a field response guided by CDC would emphasize organizing and coordinating the response through a structured incident management system, ensuring clear leadership, roles, and accountability across partners. This Advisory Incident Management structure and function provides the command and coordination necessary to respond quickly and cohesively.

Data management is another core element because timely, accurate data drive decisions about where to focus efforts, track case counts, monitor transmission, and report to stakeholders. Without solid data management, the response can’t adapt as the situation changes.

Infection control is essential to prevent further spread within health facilities and communities. Training and supervising proper use of PPE, standard precautions, and decontamination practices are foundational to protecting workers and patients and to stopping transmission chains.

Vaccination campaigns, while valuable in broader immunization efforts, aren’t typically categorized as a major field activity of the CDC’s outbreak response in this context. Immunization logistics involve different programmatic pathways and partners, and during the Ebola response in Liberia, vaccination did not constitute a standard on-the-ground CDC field activity, unlike the three core activities above.
