Analysis of the spread of dengue hemorrhagic fever with the moran index (Case study of Sukoharjo Regency in 2019)

Abstract

One of the endemic diseases that can be found in tropical areas is DHF or Dengue Hemorrhagic Fever (DHF). Dengue fever can be transmitted through Aedes aegypti mosquitoes that have been infected with the dengue virus. It is estimated that the level of dependence on DHF is always related to the infected area around it. DHF can spread to other people through mosquito bites. Sukoharjo Regency in 2018 recorded 35 cases of DHF sufferers and zero patients died. Increased up to 90% in 2019, there were 317 cases of dengue fever and 10 patients died. Therefore, the purpose of this study is to determine the autocorrelation of the spread of DHF in Sukoharjo Regency in 2019. This study used data on the number of DHF sufferers per subdistrict in Sukoharjo Regency in 2019. The research method used the calculation of the Moran Index. Calculation of Moran’s Index produced a value I = -0.181. Moran’s index value is in the range - 1≤I< 0 so that it indicates a negative autocorrelation. The correlation is classified to be a weak relationship. Negative spatial autocorrelation values indicate locations that are close to each other have values that are not close together. Subdistricts with a high number of sufferers tended to be irregular.
