What is vector control within One Health and why is cross-sector coordination critical?

• A. Reducing vector populations to lower disease risk through environment and health actions.
• B. Coordinating across health, agriculture, and environment is essential for vector control effectiveness and sustainability.
• C. Vector control is a hospital-only activity.
• D. Cross-sector coordination is unnecessary for vector control.

Answer: (B)

Vector control in a One Health framework centers on reducing disease risk by addressing the ecological and social factors that shape vector populations across humans, animals, and the environment. Cross-sector coordination is essential because vectors like mosquitoes and ticks interact with many sectors—public health, animal health, agriculture, water management, housing, and land-use planning. When health, agriculture, and environmental sectors work together, they can share surveillance data, synchronize interventions (such as habitat modification, vector control measures, livestock management, and community education), and ensure resources are used efficiently. This collaboration also helps anticipate and respond to shifts that affect transmission, like climate-driven changes in vector habitats or the emergence of new reservoirs, making control efforts more effective and sustainable over time. Without this coordination, efforts can be fragmented, duplicative, or miss critical reservoirs or habitats that lie outside a single sector’s control.
