What are the core components of Integrated Vector Management (IVM)?

• A. Surveillance only; chemical control; vaccination.
• B. Evidence-based decision-making, integrated interventions across life stages, collaboration among sectors and communities, and capacity building.
• C. Random spraying; public education; hospital treatment.
• D. Genetic modification; sterile insect technique; environmental cleanup.

Answer: (B)

Integrated Vector Management focuses on using a data-driven, collaborative approach that combines different mosquito control methods across the vector’s life cycle to reduce disease risk in a sustainable way. The essential idea is to make decisions based on evidence from surveillance and local data, selecting interventions that target multiple life stages—from larvae to adults—so actions are complementary and more effective than any single method. It also requires bringing together health, environmental, and other relevant sectors with communities to plan, implement, and monitor actions, ensuring coordination, shared goals, and efficient use of resources. Strengthening local capacity—training, robust surveillance systems, and sustained support for ongoing efforts—is crucial to keep these activities functioning over time. Why the other options don’t fit: those choices emphasize a narrow set of tools or reactive measures without the integrated, evidence-based decision framework and cross-sector collaboration that define IVM. While some listed elements can be part of vector control, they don’t capture the coordinated, multi-tool, capacity-building approach that makes IVM effective.
