Risk Factors of the Physical Environment of the House and Larva Habitat on the Incident of Malaria in the Working Area of the Tambelang Public Health Center Southeast Minahasa Regency

There were 65 occurrences of malaria episodes in the Tambelang Community Health Center in 2023. Objective: The purpose of this research was to examine the effects of the home environment and larval habitat on the occurrence of malaria in the Southeast Minahasa Regency's UPTD of the Tambelang Public Health Center. Method: This study uses a case control study design and is an analytical observational research project. There were 65 respondent samples of malaria cases, and 130 respondents made up the control group, which was chosen at a 1:2 ratio based on respondents age and sex matching the cases. Result: The results of the bivariate analysis indicate that the usage of wire gauze (OR=0.063), ventilation (OR=3.106), the density of larvae (OR=3.195), and the house wall (OR=3.167) are risk factors. With an OR=2.932 and CI (95%) = (1.514-5.679), multivariate analysis reveals that the state of the home's walls is the most significant risk factor for the incidence of malaria. Conclusion: The condition of the home's walls is the primary risk factor affecting the prevalence of malaria in Southeast Minahasa Regency. The density of larvae, the usage of wire gauze, ventilation, and an OR > 1 are additional risk factors.
