Abstract:

Objective To analyze the epidemiological characteristics of overseas imported malaria in Jiangsu Province and
explore the strategies and priorities in prevention and control，so as to provide the evidence for improving the diagnosis，treatment
and management of imported malaria. Methods The data of overseas imported malaria as well as the case epidemiological investi?
gation in Jiangsu Province from July 18，2011 to June 30，2012 were collected and analyzed descriptively for the species composi?
tion，original countries，population distribution，regional distribution，onset time，diagnosis and treatment，channels to go
abroad，and counterparts returned together with the patients. Results A total of 233 overseas imported malaria cases were report?
ed，and 226 cases（97.0%）were imported from African countries. A total of 208 cases（89.3%）were falciparum malaria，and
224 cases（96.1%）were laboratory?confirmed. The imported malaria cases were young adults who were mainly migrant farmer and
skilled male workers. There was no significant seasonal variation for onset time. Totally 145 cases（62.2%）got malaria onset in 20
days after returning home. The median time from onset to seeing doctor was two days and the median time from seeing doctor to be?
ing diagnosed was one day. The first visit health facilities by the patients were relatively scattered and the diagnostic health facili?
ties were mainly medical institutions and CDC at the county level and above（220 cases，accounting for 94.4%）. The ratio of stan?
dard treatment after malaria diagnosis was 100%. A total of 205 cases（88.0%）were workers dispatched to abroad as labor export
by the company，and 142 cases（60.9%）cases had counterparts returned together. Conclusions The situation of overseas im?
ported malaria in Jiangsu Province is severe. It is necessary to further strengthen the professional training and multi?sectoral cooper?
ation，establish the collaborative investigation mechanism for high?risk groups，and take effective prevention and control measures
to reduce the risk of overseas imported malaria.

摘要：

目的 分析江苏省境外输入性疟疾的流行病学特征并探讨其防控策略，为进一步提高输入性疟疾诊治和管理水平提供科学依据。方法 收集2011年7月18日至2012年6月30日江苏省境外输入性疟疾病例信息及个案流行病学资料，对境外输入性疟疾的虫种、来源、人群分布、地区分布、发病及诊治情况、出国途径及同行回国人员情况等进行描述性分析。结果 2011年7月18日至2012年6月30日江苏省共报告境外输入性疟疾病例233例，其中226例（97.0%）来自非洲国家，208例（89.3%）为恶性疟，224例（96.1%）为实验室确诊病例。发病人群主要为青壮年男性农民工和技术工人，发病时间无明显季节变化，145例（62.2%）病例在回国后20 d内发病。从发病到就诊时间的中位数为2 d，从就诊到确诊时间的中位数为1 d。首诊单位相对分散，确诊单位主要为县级以上医疗和疾控机构（220例，占94.4%），病例确诊后规范治疗率为100%。205例（88.0%）患者系经公司劳务派遣出国务工人员，142例（60.9%）患者有同行回国人员。结论 江苏省境外输入性疟疾疫情严峻，需进一步强化业务培训和多部门合作，针对高危人群建立协查机制，采取有力防控措施降低境外输入性疟疾的危害。
