Analysis of environmental risk factors and dynamics of transmission with incidence of filariasis in Kubu Raya district West Kalimantan Province

Filariasis is a chronic infectious disease caused by filarial worm infection and is transmitted through the bite of various types of mosquitoes. The objective of this study was to analyze the environmental risk factors and the dynamics of transmission with the incidence of filariasis. The method used was observational analytic research with the case-control design. The sample size was 126 respondents with a ratio of case: control (1:2). The data collection was conducted by interview and observation. The results showed that there was correlation between the existence of swamp (P:0,000; OR:5,200), shrubs (P:0,001; OR:6,460), type of occupation (P:0,000; OR:9,500), level of knowledge (P:0,000; OR:5,399), the habit of doing an activity at night (P:0,000; OR:7,300), habit of using mosquito repellents (P:0,004; OR:3,300), habit of using mosquito net (P:0,000; OR:7,045), and the existence of a vector (P: 0,000; OR: 7,263) with the incidence of filariasis. Meanwhile, the logistic regression test showed the most significant risk factors on the existence of shrubs (P:0,002;OR:48,700), type of occupation (P:0,004; OR:39,919), level of knowledge (P:0,013; OR:11,206), the habit of doing an activity at night (P:0,040; OR: 5,833), habit of using mosquito repellents (P:0,005; OR:10,680), and the existence of a vector with the incidence of filariasis. It can be concluded that there was a correlation between environmental risk factors and the dynamics of transmission with the incidence of filariasis, thus, prevention efforts need to be conducted by reducing risk factors and educating the public about the efforts of promotion and prevention of filariasis transmission.
