Urban Indian slums in Botswana are known for high-density populations and limited access to healthcare services, creating ideal conditions for vector-borne diseases including Zika Virus (ZIKV). The intervention included extensive community engagement, application of insecticide-treated bed nets (ITNs), and periodic environmental inspections to eliminate breeding sites. Data were collected through weekly surveillance rounds and analysed using logistic regression models. A significant reduction in ZIKV positivity rates was observed over the study period, with ITN use increasing from 30% pre-intervention to 65% post-intervention (p-value < 0. 01). Vector control measures were effective in reducing ZIKV transmission in urban slums of Botswana. Further research should explore long-term sustainability and cost-effectiveness of these interventions. Zika Virus, Urban Slums, Vector Control, Community Engagement, Logistic Regression Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
