Zika Vector Control Strategies and Their Impact on Urban Pregnant Women Health in Mozambique Cities,

Zika virus transmission in urban areas poses significant health risks to pregnant women, including neurological complications and microcephaly. A mixed-methods approach combining survey data with sentinel site surveillance for mosquito population density and Zika virus seroprevalence was employed. Logistic regression models were used to assess the impact of interventions on pregnancy outcomes. Mosquito control efforts resulted in a statistically significant reduction (p < 0.05, CI: -12% to -3%) in Aedes albopictus mosquito population density compared to baseline levels. Vector control strategies significantly reduced the risk of Zika virus exposure among urban pregnant women, although further research is needed for comprehensive evaluation. Continued monitoring and adaptive management approaches should be implemented to maintain effectiveness against vector-borne diseases in urban settings.
