Abstract

Background: Rainfall, humidity, and temperature are factors that greatly influence the dengue fever vector index. Objectives: Describe some microclimate indicators, number of cases, dengue vector index by month, correlation between indicators and evaluate the effectiveness of some Ades mosquito control measures in the district Phu Giao, Binh Duong province in 2023 – 2024. Materials and methods: Vector index, Microclimate indexes, Disease cases, households of Phu Giao district. Cross-sectional descriptive study, analysis and community intervention with a control group. Results: Rainfall is positively related to all vector and dengue indicators. Rainfall increases by 1 unit, CSNBG index and BI increase by 0.01 (p=0.007) and 0.02 (p=0.019), respectively. Humidity is inversely related to CSNBG (with r=-0.75), positively related to other vector indices and dengue fever. Temperature is inversely related to all vector and dengue indexes. Vector index is positively related to dengue. Intervention reduces incorrect vector eradication practices by 30% (CSHQ = 30%). Intervention effectiveness reduces 16% of incorrect vector eradication practices (HQCT = 16%) and p<0.001. Conclusion: As rainfall and humidity increase each month, the vector index and dengue fever increase. When temperature decreases, vector index and dengue fever increase and vice versa. If the vector index increases in each month, dengue cases increase. Health education communication is highly effective in eliminating dengue fever vectors
