目的 分析松滋市达到血吸虫病传播阻断标准后现症病人流行病学特征,为消除阶段精准治疗与防控提供科学依据。方法 收集中国疾病预防控制中心流行病学动态数据采集平台(EDDC)血吸虫病调查系统中2017—2019年松滋市血吸虫病现症病人基本信息,对其病例特征、生活生产方式等进行描述性分析。结果 2017—2019年松滋市共报告血吸虫病现症病人3 007例,其中慢性临床病例2 609例,晚期血吸虫病(晚血)病例398例,无急性病例和确诊病例报告。2019年较2017年减少1 632例,下降了94.17％。现症病人男女性别比为1.78∶1,平均年龄为(56.76±12.03)岁,40～70岁年龄组病例数占病例总数的89.60％;文化程度多为初中及以下,职业以农民为主,生活生产方式从事农业生产占95.68％;晚血病例男女性别比为2.18∶1,平均年龄为(65.70±9.60)岁,40～70岁年龄组病例数占病例总数的90.00％。晚血病例中以腹水型和巨脾型为主。现症病人中贫困户慢性临床病例占2.90％,晚血病例占8.20％。结论 松滋市血吸虫病现症病人主要是慢性病例和晚血病例,无急性病例,所有病例具有明显的社会学人口特征。需根据现症病人流行病学特点加强规范管理及随访工作,实施精准防治。
Abstract
Objective To analyze the epidemiological characteristics of patients with schistosomiasis after meeting the standards for transmission interruption of schistosomiasis in Songzi City,so as to provide a scientific basis for precise treatment and prevention and control at the elimination stage. Methods The basic information of schistosomiasis patients in Songzi City from 2017 to 2019 in the schistosomiasis survey system of the Epidemiological Dynamic Data Collection Platform (EDDC) of the Chinese Center for Disease Control and Prevention was collected.Descriptive analysis was made on its demographic characteristics,population and regional distribution,living and production modes and other characteristics. Results From 2017 to 2019,a total of 3 007 patients with schistosomiasis were reported in Songzi City,including 2 609 chronic clinical cases,398 advanced cases,and no acute cases and confirmed cases were reported.Compared with 2017,there were 1 632 fewer cases in 2019,with a decrease of 94.17％.The male-female sex ratio of current patients was 1.78∶1,the average age was (56.76±12.03) years old,and the number of cases in the age group of 40-70 years old accounted for 89.60％ of the total number of cases.Most of them had junior high school education or below,and were mainly farmers.95.68％ of them were engaged in agricultural production.The male-female sex ratio of advanced cases was 2.18∶1,the average age was (65.70±9.60) years old,and the number of cases in the age group of 40-70 years old accounted for 90.00％ of the total number of cases.Advanced cases were dominated by ascites and megaspleen.Among the current patients,chronic clinical cases in poor households accounted for 2.90％,and advanced cases accounted for 8.20％. Conclusion The patients with schistosomiasis in Songzi City are mainly chronic cases and advanced cases,but no acute cases.All cases have obvious sociological demographic characteristics.It is necessary to strengthen standardized management and follow-up work according to the epidemiological characteristics of current patients,and implement precise prevention and treatment.
