Abstract

Abstract:

Objective To identify the high risk areas and time of local dengue cases in Guangdong province. Methods Decomposing the local dengue cases to study the high risk time; Conducting purely special analysis to identify high risk areas using SaTScan software. Results The occurrence of local cases had a characteristic of seasonality, mainly occurred in September and October. Local dengue cases showed spatial heterogeneity and the most cluster located at Yuexiu, Liwan, Baiyun, Haizhu, Tianhe, Panyu and Foshan districts. Conclusion The occurrence of local dengue cases showed temporal and spatial heterogeneity. When preventing and controlling dengue occurrence in Guangdong, limited resources should be allocated reasonably and should be focused on these high risk areas and time.

Key words: Dengue, Local cases, Temporal and spatial distribution

摘要：

目的明确广东省登革热本地病例高发区域及高发时间。方法采用时间序列分解方法将2003-2012年广东省登革热本地病例进行分解, 探寻登革热高发时间;采用SaTScan中单纯空间分析方法分析广东省登革热高发区域。结果广东省登革热发生具有明显的季节性, 本地病例高发于9、10月;本地病例发生具有明显地域异质性, 登革热本地病例第一聚集区为广州市越秀区、荔湾区、白云区、海珠区、天河区、番禺区和佛山市禅城区。结论广东省登革热本地病例时空分布特征明显, 登革热防控应提前并将有限卫生资源向高发区域合理倾斜。
