Overview of Dengue Fever (DHF) incidence based on population density in Indonesia

Dengue fever (DHF) is an infectious disease caused by the dengue virus, with Aedes aegypti and Aedes albopictus mosquitoes as vectors. The prevalence of DHF globally has increased significantly, and the infection has become endemic in many regions including Indonesia. The purpose of this study was to determine the relationship between population density and the incidence of Dengue Hemorrhagic Fever (DHF) in Indonesia. This research uses a descriptive method with a population correlation study. Descriptive analysis in this study utilized the Health Mapper version 4.3.0.0 application while the population correlation test used the SPSS data processing application with the Spearman bivariate test. The population in this study is provinces in Indonesia. The independent variable in this study is population density in provinces in Indonesia, while the dependent variable in this study is the incidence of Dengue Fever (DHF) in Indonesia in 2020, 2021, and 2022. The results showed that DHF cases are directly proportional to the high population density in a province. The correlation test on dengue cases and Indonesia's population density in 2020 showed a correlation coefficient of 0.811. The correlation test between DHF cases and Indonesia's population density in 2021 showed a correlation coefficient of 0.766. The correlation test between dengue cases and Indonesia's population density in 2022 showed a correlation coefficient of 0.741. This study concluded that there is a very strong relationship between dengue fever cases and population density in various regions in Indonesia.
