- Abstract
Introduction: Dengue fever is a vector-borne viral disease in Malaysia, and the increasing incidence of the disease necessitates an investigation of its temporal course to ensure effective detection and containment. The aim of this study is to investigate the spatial and temporal distribution of dengue fever in the region. Methods: Daily confirmed dengue fever cases from a five-year epidemic in Seremban were used to generate monthly and annual total case counts for temporal analysis. Then, the Getis-Ord Gi and Global Moran's I were used to plot dengue hotspots and cluster areas. The researchers also calculated and plotted mean and standard deviation ellipses to analyse the direction of dengue case distribution, which runs from southeast to northwest. Results: The study found that there was a clustering of dengue cases in Seremban district with a z-score of 36.9 and a p-value of 0.01. The hotspot pattern in Seremban increases over time and expands every year from 2017 to 2021. Finally, the study suggests that the pattern of dengue fever outbreak in the region is likely influenced by environmental conditions related to the ecology of the Aedes mosquito. Conclusion: Spatiotemporal dengue studies provide snapshots of the location of future dengue epidemics to ensure effective detection and containment of dengue fever, which is proving difficult due to the complex interactions between relevant epidemiological factors and a range of environmental, climatic, and societal characteristics that require further investigation.
