POLA SEBARAN DAN RISIKO KEJADIAN DEMAM BERDARAH DENGUE DI KECAMATAN MEREK KABUPATEN KARO

Abstract

Dengue Hemorrhagic Fever is still one of the public health problems in the Merek District and tends to show a fluctuating increase. It was reported that in 2017 the total number of DHF cases was 38 cases with a morbidity or Incidence Rate (IR) of 9.4 / 100,000 population, while the case fatality rate (CFR) was 5.3%. DHF is caused by an imbalance between the three interacting factors, namely host, agent, and environmental factors. The use of Geographic Information System (GIS) is carried out to obtain information about the distribution of cases in each region. The purpose of this study was to determine the distribution patterns and risks that influence the incidence of dengue hemorrhagic fever (DHF) in the Merek District of Karo District. Observational research with a case-control design. The case is DHF sufferers. Control is not a sufferer of DHF. Samples were taken by simple random sampling of 62 cases and 62 controls. Where researchers do measurements on the dependent variable beforehand the effect (DHF), while the independent variables are retrospective to determine whether there is a risk of DHF events. The statistical tests used were Chi-Square (bivariate analysis) and Logistic Regression (multivariate analysis). The results of the bivariate analysis showed risk factors for age, education, use of wire mesh and eradication of mosquito nests related to the incidence of DHF. The results of multivariate analysis showed that the risk factor that played a role in the incidence of DHF was the eradication of mosquito nets. The incidence of DHF increases in people who do not have the habit of PSN (Mosquito Nest Eradication) for that practice of cleaning and draining water reservoirs, closures, and burial of used goods.
