Spatial and Temporal Analysis of Dengue Cases in Peninsular Malaysia: A five-year analysis from 2016 to 2020

Abstract

Dengue fever is one of the most common vector-borne diseases spread by Aedes albopictus and Aedes aegypti mosquitos. The regional and temporal trends of dengue cases in East Malaysia are investigated in this study. The study aims to assess the prevalence of dengue cases across 91 districts in Peninsular Malaysia from 2016 to 2020 and, hence, to identify dengue disease's hotspot and cold spot regions. By using ArcGIS, summarised yearly data of dengue cases were analysed. The study results showed that dengue cases mainly occurred in the central part of Peninsular Malaysia.
