Climate variability (temperature, humidity, rain intensity and wind speed) and dengue hemorrhagic fever case correlations in Depok City in 2009-2018

Abstract

Climate issues caused by industrial pollutant has affected the spread of vector-borne diseases such as Dengue Hemorrhagic Fever (DHF). DHF cases are suspected to have links with the everchanging environmental climate conditions. Using an ecological design-based study, this research aims to determine the correlations between climate variability and the DHF cases at Depok City in a time period from 2009 to 2018. This study utilizes secondary data in which DHF cases were collected through the records of Department of Health of Depok City, and temperature, humidity, rain intensity, and wind speed from Depok City Meteorological, Climatological, and Geophysical Agency. Analytical method consists of univariate analysis and bivariate analysis which is shown by a correlation value and linear regression between the variables. Results revealed that there was a significant relationship between temperature and the number of DHF cases (p-value = 0.023, r = - 0.645) and also between humidity and the number of DHF cases (p-value = 0.016, r = 0.673). No significant correlations were found within rain intensity and wind speed variables. In conclusion, this study showed that the effects of climate temperature and humidity changes also affect the rise and declining number of DHF cases in this study location.
