Abstract: Objective To understand the epidemic situation and influencing factors of malaria in Jiangsu Province and grasp the regularity and trend of the epidemic. Methods According to the provincial malaria transmission situation and characteristics, Sihong County of Suqian City, which had more original cases, and Baoying County of Yangzhou City, which had more import cases, were chosen as the malaria surveillance sentinels at the state level; six counties, Yixing County of Wuxi City, Suining County of Xuzhou City, Wujin District of Changzhou City, Haian county of Nantong City, Ganyu County of Lianyugang City, and Xuyi county of Huaian City were chosen as the malaria surveillance sentinels at the provincial level. The data of basic status, blood tests of feverish patients, case studies of malaria patients, investigations and disposals of epidemic focuses and others were collected and analyzed. Results There were 92 484 blood test samples from feverish patients in the eight surveillance sentinels in 2014, and the average rate of blood tests was 1.15%. Totally 61 cases were plasmodium positive, and the positive rata was 0.07%. All of the 61 cases were foreign imported patients diagnosed by laboratory. After the direct network reporting, the review of the blood slides and epidemiological individual surveys were finished in 3 days, and the investigations and disposals of epidemic focuses were finished in 7 days. The epidemiological individual surveys of these 61 cases showed that 37.70% (23/61) of the first?time consultancy was mainly in the county level CDC, and 50.82% (31/61) in county level medical organizations. The making definite diagnosis of malaria also focused on the county level, 45.90% (28/61) in county level CDC and 47.10 % (29/61) in county level medical organizations. The definite diagnostic rate of fist?time consultancy was 90.16% (55/61). Totally 48 malaria patients had been sent to abroad by their companies, and 34 had fellow crew. Conclusions The malaria surveillance sentinels in Jiangsu Province play a good role on the surveillance function of malaria, and effectively promote the elimination of malaria in whole province. In the future, the malaria surveillance should establish a multi?sectoral cooperation and investigation mechanism, and strengthen the screening of the high?risk population and health education.

摘要: 目的 了解江苏省疟疾流行现状,掌握疟疾流行规律和趋势。方法 根据全省疟疾流行程度与特征,选择原本地病例较多的宿迁市泗洪县和输入性病例较多的扬州市宝应县为国家级疟疾监测哨点;选择无锡市宜兴市、徐州市睢宁县、常州市武进区、南通市海安县、连云港市赣榆县和淮安市盱眙县6个县(市、区)为省级疟疾监测哨点。收集疟疾监测哨点基本情况以及发热病人血检、疟疾病人个案调查、疫点调查和处置等监测数据。结果 2014年江苏省8个疟疾监测哨点共血检发热病人92 484人次,平均血检率为1.15%;检出疟原虫阳性61例,阳性率为0.07%。61例疟疾病例均为实验室诊断的境外输入性病例,并在网络直报3 d内完成血片复核和流行病学个案调查、7 d内完成疫点调查与处置。流行病学个案调查发现,61例疟疾病例初次就诊主要集中在县级疾控机构(37.70%,23/61)和县级医疗机构(50.82%,31/61),明确诊断也集中在县级疾控机构(45.90%,28/61)和县级医疗机构(47.10%,29/61);初次就诊确诊率为90.16%(55/61);48例由公司外派出国,34例有同行人员。结论 江苏省疟疾监测哨点较好地发挥了监测作用,有效推动了全省消除疟疾工作。今后的疟疾监测工作应建立多部门合作模式,形成协查机制,加强对高危人群的主动筛查和健康宣教。
