摘要

空间分析通过评估疾病动态和确定风险区域，在病媒控制中发挥关键作用。虽然有许多研究调查了马来西亚的登革热发病率，但很少有研究专门调查持续30天以上的长期局部登革热流行。本研究旨在分析2017 - 2021年雪兰莪州登革热热点的分布和模式。方法从谷歌地图中获取登革热热点坐标，利用ArcGIS进行制图。生成热图以可视化流行病学周和地区的时空热点格局。开展热点分析，确定登革热病例高发地区。结果共发现登革热热点400余个，主要集中在贡巴克、葫芦岛、巴生和花瓣岭地区，人口密度均超过1000人/ km2。登革热高发热点（≥70 /周）出现在1 - 3月、6 - 9月和10 - 12月3个季节。结论本研究为雪兰莪州登革热长期暴发的时空分布提供了新的认识。研究结果可为高风险地区有针对性的病媒控制战略和政策干预提供信息。

Spatiotemporal dynamics of dengue hotspots in an urbanizing landscape: A five-year analysis in Selangor, Malaysia

Introduction

Spatial analysis plays a crucial role in vector control by assessing disease dynamics and identifying risk areas. While numerous studies have examined dengue incidence in Malaysia, few have specifically investigated prolonged localized dengue epidemics lasting more than 30 days. This study aims to analyze the distribution and patterns of dengue hotspots in Selangor from 2017 to 2021.

Methods

Dengue hotspot coordinates were obtained from Google Maps and mapped using ArcGIS. Heat maps were generated to visualize temporal and spatial hotspot patterns across epidemiological weeks and districts. Hotspot analysis was conducted to identify areas with a high frequency of dengue cases.

Results

Over 400 dengue hotspots were identified, primarily concentrated in Gombak, Hulu Langat, Klang, and Petaling districts characterized by high population densities exceeding 1000 individuals per km². Peak dengue hotspot occurrences (≥70 per week) were observed during three seasonal periods: January–March, June–September, and October–December.

Conclusion

This study provides new insights into the spatial-temporal distribution of prolonged dengue outbreaks in Selangor. The findings can inform targeted vector control strategies and policy interventions in high-risk areas.
