Abstract

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.
