Abstract

Background: DHF is one of the contagious diseases that remains a major problem both in the world and in Indonesia. Purbalingga Regency is one of the regencies in Central Java that constantly reports DHF cases every year. The increase of DHF cases in Purbalingga Regency in January-June 2019 almost tripled compared to the number of cases in 2018. The residential environment plays a significant role in the transmission of DHF. Therefore, it is necessary to conduct research on environmental factors associated with the incidence of DHF in Purbalingga Regency. Method: This study used a case-control study design. The data were collected using questionnaires through interviews and observations. The total sample of 408 respondents was taken from two subdistricts with the highest cases. Univariate, bivariate (chi-square), and multivariate (Logistic Regression) analysis were employed in this study to analyze the relationship between environmental factors with the incidence of DHF. Result: The results of the study indicate that environmental factors associated with the incidence of DHF in Purbalingga Regency in 2019 were the availability of mosquito gauze (OR: 2.30; 95% CI: 1.379-3.829) and the presence of discarded trash (OR: 1.91; 95% CI: 1.249-2.933). Conclusion: The availability of mosquito gauze and the presence of discarded trash were environmental factors associated with the incidence of DHF in Purbalingga Regency. Therefore, efforts are required to promote health regarding the mosquito nest eradication (PSN) 3M plus and sustainable waste management among the inter-related sectors in the context of controlling DHF in Purbalingga Regency.
