Abstract:

Objective To analyze the malaria prevalence and epidemic characteristics in Jiangsu Province in 2011 so as to
provide a basis for drawing up and adjusting effective malaria elimination strategies and measures. Methods The reported malar?
ia cases from the Internet reporting system and epidemiological data of malaria were collected and analyzed statistically in Jiangsu
Province. Results A total of 374 malaria cases were reported in Jiangsu Province in 2011 with the incidence of 0.05 /10 000
which was similar to the number of cases in 2010. There were 13 cases of local vivax malaria which decreased by 87.00% com?
pared with 100 cases in 2010. There were 361 imported cases including 309 imported falciparum malaria cases which increased by
49.00% compared with 207 cases in 2010. The imported falciparum cases mainly distributed in Yangzhou,Nantong,Huai’ an and
Taizhou cities which are located in central Jiangsu and coastal areas of northern Jiangsu. The number of imported falciparum malar?
ia cases of these four cities accounted for 66.02% among the total cases in Jiangsu Province. There were 7 imported quartan malaria
cases that were first reported and 14 imported ovale malaria cases. Conclusions The local vivax malaria infections in Jiangsu
Province decrease significantly and the endemic areas reduce significantly. However the imported falciparum malaria cases are in?
creasing significantly year by year and the infected plasmodium parasites show diversities. Therefore,to achieve the target of malar?
ia elimination in Jiangsu on schedule,it needs to continue to strengthen the personnel training of primary health care facilities and
the disease control agencies,and strengthen the health education for export staffs and the monitoring and surveillance of the return?
ee.

摘要:

目的 分析江苏省2011年的疟疾疫情及流行特征,为制订和调整适合本省有效的消除疟疾策略和措施提供科学依据。方法 收集全省网络报告疟疾疫情和专报系统的流行病学调查资料,并进行统计分析。 结果 2011年江苏省共报告疟疾374 例,发病率为0.05/万,与2010 年病例数基本持平。本地感染间日疟病例13 例,较2010 年的100 例下降了87.00%;输入性疟疾病例361例,其中境外输入性恶性疟病例309例,较2010年的207例上升了49.27%,主要分布在江苏中部和苏北沿海的扬州、南通、淮安、泰州市,该4市输入性恶性疟病例数占全省总数的66.02%(204/309)。2011年江苏省首次报告输入性三日疟7例,输入性卵形疟14例。 结论 江苏省本地感染间日疟病例明显下降,流行范围明显缩小;但境外输入性疟疾仍呈明显上升趋势,且感染疟原虫虫种呈多样性。因此,为如期实现全省消除疟疾目标,仍需继续加强对基层医疗机构和疾病预防控制机构相关人员的培训,加强对劳务输出人员的健康教育和回国人员的监测管理。
