Analysis of temperature, humidity, rainfall, and wind velocity on dengue hemorrhagic fever in Bandung municipality

The trend of dengue hemorrhagic fever prevalence every year continues to show an increase and number of deaths. This is due to an increase in the population of aedes aegypti mosquitoes. Climate change has the potential to affect mosquito-borne diseases, including dengue fever, which is a vulnerability for residents in Bandung Municipality. This research aims to analyse the relationship between temperature, humidity, rainfall, and wind velocity with dengue hemorrhagic fever in Bandung Municipality. The methodology research used in this study is descriptive analysis with a cross-sectional approach. This research was conducted in Bandung Municipality. The study samples were taken from data on dengue hemorrhagic fever sufferers, as well as data on temperature, humidity, rainfall, and wind speed. This study used secondary data. The data collected is in the form of data on temperature, humidity, rainfall, and wind speed, and the number of cases. To assess the correlation between variables using the person correlation test. To test the effect of all four variables simultaneously on the incidence of dengue hemorrhagic fever using a linear regression test. Average value of air temperature is 25.8°C, air humidity is 69.9%, rainfall is 201.5 mm, and the wind velocity is 1.8 knots. The prevalence of dengue hemorrhagic fever is 232.5 cases. There is a significant relationship between humidity with dengue hemorrhagic fever prevalency (p = 0.018, r = 0.873). Wind velocity with dengue hemorrhagic fever prevalency (p = 0.018, r = 0.629). The result of the coefficient of determination test on temperature, humidity, rainfall, and wind velocity with DHF cases is R2 = 0.745. The increase in dengue prevalence in Bandung City occurred from January to June, the decrease in prevalence occurred from July to December. Variations in temperature, humidity, rainfall and wind speed can simultaneously affect the incidence of dengue fever in Bandung. Therefore, in the future it is necessary to increase mosquito nest eradication activities to prevent dengue transmission considering that this disease has the potential to spread at any time.
