Investigation of risk factors for household-based dengue virus infection in Borobudur Subdistrict, Magelang, Indonesia.

INTRODUCTION

Dengue infection poses a serious threat to global public health, including Indonesia. The rapid spread and significant economic impact are crucial concerns for control efforts. Investigating risk factors of dengue virus infection is necessary to formulate effective strategies, particularly at the household level. This study aims to investigate contributing risk factors to dengue virus transmission in the Borobudur Subdistrict, Magelang, Indonesia, an area with persistently high dengue infection mortality rates.

METHODS

This study adopted a case-control design and utilized secondary data collected from six villages in the Borobudur Subdistrict. A total of 111 households (37 cases and 74 controls) participated in the study and completed a questionnaire encompassing: 1) Sociodemographic data; 2) Healthy housing components; 3) Sanitation and behavioral components; and 4) Dengue infection prevention practices. Data were analyzed bivariately using statistical software to identify differences in group proportions.

RESULTS

The findings of this study indicate that the presence of stagnant water (odds ratio [OR]: 5.02) and mosquito larvae (OR: 4.80) around the house, morning sleep habits (OR: 6.97), and lack of participation in anti-dengue programs (OR: 3.23) are significant risk factors (p<0.05) for dengue infection. However, no significant differences (p>0.05) were found in healthy housing components between the case and control groups.

CONCLUSIONS

This study has identified contributing risk factors to dengue virus transmission in the Borobudur Subdistrict. These results can serve as a foundation for designing more effective intervention programs for dengue infection and future prevention efforts.
