摘要: 目的 分析云南省保山市恙虫病流行特征,为保山市恙虫病防控提供科学依据。方法 运用描述性流行病学方法,对国家疾病监测信息报告管理系统报告的保山市2006-2016年恙虫病监测数据资料进行分析,数据比较采用χ2检验。结果 保山市2006-2016年累计报告恙虫病5 205例,年平均发病率为18.82/10万。发病率由2006年的0.57/10万上升至2016年的37.74/10万,呈现逐年上升趋势(χ2趋势=2 762.798,P=0.000),发病率增加了65倍。发病高峰期为7-10月,发病数占全年病例数的88.90%。男、女性发病数分别占总发病数的49.91%和50.09%,年平均发病率分别为18.32/10万和19.34/10万。各年龄组均有病例发生,病例主要集中在25~64岁人群,占总病例数的55.62%;发病率以1~7岁儿童最高,其次是50~69岁中老年人群。发病人群逐年增多,其中以农民(占64.92%)占比重最大且呈现逐年增加的趋势;其次是散居儿童(占19.27%)和学生(占11.39%)。发病率以龙陵县最高,隆阳区最低;农村是恙虫病的高发地区,2006-2016年农村恙虫病发病率呈现波动递增的态势。结论 保山市恙虫病发病水平较高,疫情重点地区为农村,重点人群为儿童和中老年人。建议根据疾病流行规律,针对重点地区、重点人群,着力加强疾病监测、健康教育等工作,降低恙虫病发病水平。

Abstract: Objective To analyze the epidemiological characteristics of scrub typhus in Baoshan, Yunnan province, China, and to provide a scientific basis for the prevention and control of scrub typhus in Baoshan. Methods The data of scrub typhus in Baoshan from 2006 to 2016 was collected from the National Information Reporting System of Infectious Diseases, and then analyzed using the descriptive epidemiological method and chi-square test. Results A total of 5 205 cases of scrub typhus were reported in Baoshan from 2006 and 2016, with a mean annual incidence rate of 18.82/100 000. The incidence rate of the disease increased by 65 times, from 0.57/100 000 in 2006 to 37.74/100 000 in 2016, showing a rising trend over the years (χ2=2 762.798, P=0.000). The peak incidence period of the year was from July to October, with the number of cases accounting for 88.90% of the total cases. The numbers of male and female patients accounted for 49.91% and 50.09% of the total number of cases, respectively; the mean annual incidence was 18.32/100 000 and 19.34/100 000, respectively. The cases of scrub typhus occurred in all age groups, with the majority aged 25 to 64 years old (55.62%); the highest incidence was among children aged 1 to 7 years old, followed by those aged 50 to 69 years old. The number of patients increased over the years, among whom farmers accounted for the largest percentage (64.92%) and showed an upward trend, followed by scattered children (19.27%) and students (11.39%). The incidence rate was highest in Longling county and lowest in Longyang district. There was a high incidence of scrub typhus in rural areas, with a fluctuating and increasing trend from 2006 to 2016. Conclusion The incidence of scrub typhus in Baoshan is relatively high, especially in the rural areas and among children, middle-aged or elderly population. Based on the epidemiology of scrub typhus, disease surveillance and health education should be enhanced in those areas and populations to reduce the incidence of the disease.
