虽然中国在疟疾控制方面取得了巨大成功，但输入性疟疾已成为消除疟疾背景下的主要挑战。回顾性分析江苏省2001-2011年输入性疟疾流行病学特征，并对输入性疟疾高危人群进行分析。方法收集江苏省2001 - 2011年输入性疟疾病例资料，采用传染病监测系统和病例调查报告进行分析。报告描述了流行病趋势，并探讨了劳务输出趋势与从其他国家输入疟疾趋势之间的相互关系。从2001年到2011年，918例疟疾病例和6例疟疾死亡是由于其他国家输入的疟疾，占所有疟疾病例的12.4%和所有疟疾死亡的100%。在此期间，每年本土病例数从1 163例减少到13例，而输入病例数从86例增加到366例。其他国家输入病例与其他省份输入病例的相对比例也从0.0%（0/86）上升至97.0%（350/361）。受影响最大的人口群体是男性（897例，97.7%）和成年人（20-50岁：857例，93.4%）。所有918例病例均有近期到疟疾流行区旅行的历史，旅行的主要目的是海外劳务（848例，92.4%）。病例主要来自非洲国家（855例，93.1%）。恶性疟原虫最常见（733例，占79.8%）。从其他国家输入的疟疾病例的增加与江苏对非洲投资的增长（R2 = 0.8057）和江苏向非洲输出的劳动力数量的增加（R2 = 0.8863）有关。2001年至2011年，江苏省从其他国家输入的疟疾病例数持续增加，而本地获得的病例数急剧下降。这一趋势可能归因于中国对非洲的投资增加以及在非洲工作的中国劳工人数增加。应针对这一高危人群采取预防措施，加强监测和应对系统，防止江苏省局部死灰复燃。
While great success in malaria control has been achieved in China, imported malaria has become a major challenge in the context of malaria elimination. This retrospective study describes the epidemiological profile of imported malaria and identifies the at-risk population during the period of 2001–2011 in Jiangsu Province. Data on imported malaria cases in Jiangsu Province from 2001 to 2011 were collected from the infectious disease surveillance system and case investigation reports. Epidemiological trends were described and correlations between trends in exported labour and malaria imported from other countries were explored. From 2001 to 2011, 918 malaria cases and six malaria deaths were due to malaria imported from other countries, accounting for 12.4% of all malaria cases and 100% of all malaria deaths. During this time period the annual number of indigenous cases decreased from 1,163 to 13 while the number of imported cases increased from 86 to 366. The relative proportion of cases imported from other countries versus other provinces also increased from 0.0% (0/86) to 97.0% (350/361). The most affected demographic groups were males (897 cases, 97.7%) and adults (20–50 years old: 857 cases, 93.4%). All 918 cases had a recent travel history to malaria-endemic areas and the main purpose for travel was overseas labour (848 cases, 92.4%). The cases were mainly acquired from African countries (855 cases, 93.1%). Plasmodium falciparum was the most common species (733 cases, 79.8%). The increase in malaria cases imported from other countries was associated with the growth of investment to Africa from Jiangsu (R2 = 0.8057) and the increasing number of exported labourers to Africa from Jiangsu (R2 = 0.8863). From 2001 to 2011 in Jiangsu Province, there was a consistent increase in the number of malaria cases imported from other countries while the number of locally acquired cases sharply declined. This trend may be ascribed to the increasing investment from China to Africa and the rising number of Chinese labourers working in Africa. Preventative efforts should be targeted to this high-risk group and the surveillance and response system should be strengthened to prevent local resurgence in Jiangsu.
