Summary
Community empowerment significantly improved dengue vector control in Cuba. This strategy enhanced community involvement and knowledge, leading to a 53% reduction in Aedes aegypti infestation, demonstrating its effectiveness over routine programs.
Area of Science:
- Public Health
- Vector-Borne Disease Control
- Community-Based Interventions
Background:
- Vertically organized dengue vector control programs face sustainability challenges.
- There is a growing need to shift focus towards community-based strategies for effective dengue management.
Purpose of the Study:
- To evaluate the effectiveness of a community empowerment strategy integrated with routine dengue vector control.
- To assess the impact of the intervention on community participation, knowledge, practices, and Aedes aegypti infestation levels.
Main Methods:
- A cluster randomized controlled trial was conducted in La Lisa, Havana City, Cuba.
- 16 intervention clusters received a community empowerment strategy (organization, surveillance, capacity building, community work) alongside routine control.
- 16 control clusters continued with routine activities only.
Main Results:
- Community participation scores increased significantly in intervention clusters (1.4 to 3.4).
- Knowledge of breeding sites improved by 52.8% in intervention vs. 27.5% in control clusters.
- Adequate household control practices increased by 36.2% in intervention clusters.
- Breteau indices (BI) were 53% lower in intervention clusters compared to control clusters over the study period.
Conclusions:
- Community empowerment strategies enhance routine dengue vector control efforts.
- Increased community involvement and knowledge are key drivers of improved Aedes aegypti control.
- This integrated approach offers a more sustainable and effective model for dengue prevention.
