2005-2017年广东和云南省登革热高发区本地登革热流行病学特征比较研究

Epidemiological characteristics of indigenous in the high-risk areas of Guangdong and Yunnan provinces, China, from 2005 to 2017:a comparative study

目的比较广东和云南省登革热高发区的本地登革热病例流行病学特征。方法收集2005-2017年的登革热病例信息,包括病例所在的现地址、性别、年龄、职业、发病时间、确诊时间和病例是否为输入病例等信息,采用SPSS 20.0和R 3.5.0软件进行统计学分析。结果从2005-2017年广东省研究的高发区域发生登革热本地病例共有44 676例,云南省高发区域发生登革热本地病例共有3 676例。2个研究区域登革热本地病例的职业、年龄、性别及发病和确诊时间间隔差异均有统计学意义(χ2=989.647、98.666、7.429,P=0.000、0.000、0.006;U=5.360,P=0.000),其中广东省高发区登革热本地病例主要为家务及待业者,云南省主要为商业服务者;广东省高发区域登革热病例在各个年龄段广泛分布,云南省主要集中于青壮年;在性别分布中,广东省高发区域登革热的男性比例低于云南省。结论广东和云南省登革热本地病例整体均呈现上升趋势,两地的登革热本地病例流行病学特征存在明显差异。

Objective To compare the epidemiological characteristics of indigenous dengue cases in the high-risk areas of Guangdong and Yunnan provinces, China. Methods The data of dengue cases from 2005 to 2017 were collected, which included the present address, sex, age, occupation, time of onset, time of diagnosis, and whether the cases were imported or not. Statistical analysis was performed using SPSS 20.0 and R 3.5.0. Results From 2005 to 2017, there were 44 676 and 3 676 indigenous dengue cases in the high-risk areas of Guangdong and Yunnan provinces, respectively. The two study regions were significantly different in the occupation, age, sex, and interval from onset to diagnosis for indigenous dengue cases( χ2=989.647, P=0.000;χ2=98.666, P=0.000;χ2=7.429, P=0.006;U=5.360, P=0.000). Besides, the indigenous dengue cases were mainly household and unemployed workers in the high-risk areas of Guangdong province and commercial service workers in Yunnan province. The indigenous dengue cases were widely distributed in all ages in the high-risk areas of Guangdong province, but concentrated in young adults in Yunnan province. The male proportion of dengue cases in the high-risk areas of Guangdong province was lower than that in Yunnan province. Conclusion The numbers of indigenous dengue cases in Guangdong and Yunnan provinces rose from 2005 to 2017, and there was a significant difference in their epidemiological characteristics between the two provinces.
