Abstract:

Objective To analyze the prevalent characteristics of malaria in Jiangsu Province in 2009 so as to provide the reference for making effective measures of malaria control. Methods The reported cases and epidemiological data of malaria in Jiangsu Province were analyzed statistically and described. Results A total of 389 malaria cases were reported with an incidence rate of 0.05/10 000 in 2009, 41.77% lower than that in 2008. There were reported malaria cases in all thirteen cities, 44.73% of all the cases were from Xuzhou, Suqian, and Huaian. There were 192 local malaria infectors with Plasmodium vivax (P.v), 73.44% of that in Jiangsu Province, which had a major distribution in Xuzhou, Suqian, and Huaian. There were 96 imported infectors of P.v, mainly spreading over the south part of Jiangsu Province with high percentage of migrant workers. There were 101 imported infectors of Plasmodium falciparum (P.f), 71.19% higher than that in 2008, mainly spreading in the central and north part of Jiangsu Province with a high percentage of workers who worked abroad. Conclusions The results show a decreased trend of malaria incidence in Jiangsu Province, however, the malaria situation in north part to the Huaihe River is still instable, and there are increasing imported cases of P.f as well. It is necessary to formulate the policy and measures to strengthen malaria control in target areas, especially the monitoring and management of workers who once worked abroad.

摘要：

目的 分析2009年江苏省疟疾流行特征，为制订有效防治措施提供参考依据。方法 对全省网络报告的疟疾疫情和流行病学调查资料进行统计和描述性分析。 结果 2009年江苏省共报告疟疾389例，发病率为0.05/万，较2008下降41.77%。全省13个市均有疟疾病例报告，徐州、宿迁和淮安3市报告病例数占全省病例总数的44.73%。389例疟疾病例中，本地感染间日疟192例，占全省本地感染间日疟病例总数的73.44%，主要分布于疟疾发病率较高的徐州、宿迁、淮安3市；省外输入性间日疟病例96例，主要分布于外来务工人员较多的苏南地区；国外输入性恶性疟病例101例，较2008年上升71.19%，主要分布于出国务工人员较集中的苏中和苏北地区。结论 江苏省疟疾发病呈下降趋势，但淮河以北局部地区疟疾疫情仍不稳定，输入性恶性疟日趋增多。应制订相关政策和措施，加强重点地区疟疾防治，特别要加强对全省劳务输出等归国人员的监测和管理。
