The relationship between dengue vector and climate factors in Ha Tinh province, 2019 - 2020

Abstract

This is a cross-sectional study conducted in 13 communes/wards of Ha Tinh province from September 2019 to August 2020 to
explore the relationship between dengue vector transmission and climate factors. The study collected weather data from the provincial hydro-meteorological center and collected samples of larvae and larvae every month from 13 communes/wards in 13 districts/towns / cities across the province. There was a total of 7800 vector sample collections. Analysis of the correlation coeffcient showed a statistically signifcant association between monthly temperature, rainfall, humidity, and mosquito
density index (p < 0.05). Risk communication should pay attention to the forecast of changes in climatic factors such as rainfall, humidity, and temperature to have a plan to prevent the development of dengue vectors.
