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.

目的

了解江苏省疟疾疫情及影响因素，掌握疟疾流行规律和趋势。

方法

根据全省疟疾传播情况及特点，选择原发病例较多的宿迁市泗洪县和输入病例较多的扬州市宝应县作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、淮安市盱眙县6个县（市、区）作为省级疟疾监测哨点。收集分析基础状况、发热病人血检、疟疾病例个案调查、疫点调查处置等资料。

结果

2014年8个监测哨点共采集发热病人血检标本92484份，平均血检率为1.15%。疟原虫阳性61例，阳性率为0.07%。61例均为实验室确诊的境外输入病例。直报后，血片复核及流行病学个案调查3天内完成，疫点调查处置7天内完成。61例流行病学个案调查显示，首诊咨询主要在县级疾控机构的占37.70%（23/61），在县级医疗机构的占50.82%（31/61）。疟疾确诊也集中在县级，县级疾控机构占45.90%（28/61），县级医疗机构占47.10%（29/61）。首诊咨询确诊率为90.16%（55/61）。48例疟疾病人中有48例被公司派往国外，34例有同船船员。
