To assess the effectiveness of an integrated, community-based environmental management strategy compared with routine vector control in suppressing Aedes aegypti infestation.
Cluster randomized trial conducted across 32 circumscriptions (approximately 2,000 inhabitants each) in Guantanamo, Cuba (ISRCTN88405796).
Clusters were randomly allocated to routine Aedes control alone (entomological surveillance, source reduction, selective adulticiding, and health education; n=16) or routine control combined with community-based environmental management (n=16).
Infestation outcomes, including house index, Breteau index, and pupae per inhabitant, were evaluated through follow-up ending February 2006.
Infestation levels were comparable at baseline between intervention and control clusters for house index (0.25% vs 0.20%) and pupae per inhabitant (0.44x10^-3 vs 0.29x10^-3).
At trial completion, intervention clusters achieved significantly lower house indices than routine control clusters (rate ratio 0.49, 95% CI 0.27 to 0.88).
Intervention clusters also demonstrated a significant reduction in pupae per inhabitant compared with control clusters (rate ratio 0.27, 95% CI 0.09 to 0.76).
