Correlational study of climate factor, mobility and the incidence of Dengue Hemorrhagic Fever in Kendari, Indonesia

Abstract

Objective

The DHF is an endemic in Kendari, Southeast Sulawesi province, Indonesia. The Incidence Rate (IR) of DHF in Kendari had decreased since 2016, 372.8 per 100,000 to 25.1 per 100,000 in 2017. Thus, this study aimed to examine the correlation of climate factors, including average temperatures, relative humidity, wind speed, and mobility on the incidence of Dengue Hemorrhagic Fever (DHF) in Kendari.

Method

This study used an ecological study or correlational study design conducted in Kendari, Southeast Sulawesi Province. The population was the aggregate data of monthly DHF incidence recorded in the Health Department of Kendari in 2014–2018. The data were analyzed using Pearson and Rank Spearman correlation tests.

Results

The present study showed a positive correlation between average (p = 0.048, r = 0.257), relative humidity (p = 0.001, r = 0.413), mobility (p = 0.045, r = 0.586) with the incidence of DHF in Kendari in 2014–2018 meanwhile, the wind speed (p = 0.589, r = −0.071) did not show a significant correlation with the incidence of DHF.

Conclusion

The climate pattern, especially the average temperature, relative humidity, and mobility, should be monitored to control the DHF disease.
