Abstract:

Objective To compare the characteristics of dengue fever epidemic between Ruili and Jinghong in Yunnan province, China, and to provide a basis for the precise prevention and control of dengue fever in the two cities. Methods The information about local and imported cases of dengue fever was collected in Ruili and Jinghong, Yunnan province from 2006 to 2018, and SPSS 22.0 and R 3.6.2 softwares were used for statistical analysis. Results From 2006 to 2018, Ruili reported a total of 3 022 cases of dengue fever, of which 59.13% were imported cases (59.00% were imported from abroad) and 40.87% were local cases. Among 3 923 cases in Jinghong, imported cases accounted for 3.08% (3.01% were imported from abroad), and local cases accounted for 96.92%. The number of imported cases in Ruili was 14.77 times that in Jinghong. The imported cases in both cities were mainly 16 to 45 years old, and mostly from Southeast Asian countries, especially Myanmar. There were statistically significant differences in sex, age, occupation, and the interval from disease onset to diagnosis of either imported or local cases between the two cities (χ2=7.529, 14.169, and 201.686, all P<0.05; χ2=18.342, 43.723, and 557.247, all P<0.001; Mann-Whitney U=75 032.500 and 2 116 735.000, both P<0.001). Conclusion Most of cases of dengue fever are imported in Ruili but local in Jinghong. Authorities of the two cities should strengthen the surveillance of cases of dengue fever, promptly detect, isolate, and treat cases, and take measures to deal with the epidemic in time.

摘要:

目的 比较云南省瑞丽和景洪市登革热流行特征,为两市登革热精准防控提供依据。方法 收集2006-2018年云南省瑞丽及景洪市登革热本地和输入病例信息,采用SPSS 22.0和R 3.6.2软件进行统计学分析。结果 2006-2018年,瑞丽市共报告登革热病例3 022例,其中输入病例占59.13%(59.00%为境外输入),本地病例占40.87%;景洪市报告的3 923例病例中,输入病例占3.08%(其中3.01%为境外输入病例),本地病例占96.92%;瑞丽市输入病例数是景洪市的14.77倍,两市输入病例年龄主要集中在16~45岁,主要来源于东南亚国家,尤其是缅甸。两市的输入病例和本地病例在性别、年龄、职业和发病至诊断间隔时间上差异均有统计学意义(χ2=7.529、14.169、201.686,均P<0.05;χ2=18.342、43.723、557.247,均P<0.001;Mann-Whitney U=75 032.500、2 116 735.000,均P<0.001)。结论 瑞丽市登革热病例境外输入较多,景洪市以本地病例为主;建议两市相关部门加强登革热病例监测,及时发现、隔离、治疗和采取疫情处置措施。
