Epidemiological Assessment of Dengue Fever Transmission in Coastal Fishing Villages of Mozambique,

Dengue fever is a significant vector-borne disease affecting coastal communities in Mozambique. A mixed-method approach combining entomological surveys with cross-sectional household interviews to evaluate vector presence and infection rates, alongside demographic data collection. Mosquito populations were predominantly Aedes aegypti, identified as the primary dengue virus carrier. The prevalence of dengue antibodies among villagers was found at 35% in the surveyed area. The study highlights high transmission risks due to vector presence and human behaviour patterns favoring mosquito breeding sites. Enhanced community education on dengue prevention, including proper waste management and water storage practices to reduce breeding grounds for mosquitoes. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
