Abstract: Objective　To analyze the epidemic situation of malaria in Jiangsu Province in 2019, so as to provide the scientific basis for the development of the strategy for the prevention of re⁃introduction of imported malaria. Methods　The malaria case report information, epidemiological case investigation information, epidemic foci investigation and management report in Jiangsu Province in 2019 were collected, and all epidemiological data were descriptively analyzed. Results　A total of 244 malaria cases were reported in Jiangsu Province in 2019, and all cases were laboratory⁃confirmed overseas imported cases, including 4 cases with vivax malaria, 206 cases with falciparum malaria, 12 cases with malariae malaria and 22 cases with ovale malaria. In 2019, there were 12 malaria cases progressing into severe cases in Jiangsu Province, with one death. Nanjing, Nantong, Lianyungang, Taizhou and Changzhou cities contributed the largest number of malaria cases in 2019, with the number of malaria cases accounting for 59.84% of total cases in Jiangsu Province. The infections occurred in Papua New Guinea (2 cases), Pakistan (1 case) and 27 African countries (241 cases), including Angola, the Democratic Republic of the Congo, Nigeria, Equatorial Guinea, Cote d'Ivoire and so on. There were 77 cases (31.55%) with a visit to doctor on the day of onset, and 146 cases (59.84%) within 1 to 3 days after onset. In addition, there were 149 cases (61.06%) with definitive diagnosis at the first visit and 77 cases (31.55%) diagnosed within 1 to 3 days after the visit, and the mean duration from the visit to definitive diagnosis was (0.80 ± 1.59) d, which significantly shortened as compared to that (1.34 d ± 2.59 d) in 2018 (U = 2.53, P < 0.05). Conclusions　Intensifying the surveillance and management of imported malaria and improving the diagnostic capability of imported malaria and the treatment of severe malaria cases are required to consolidate the achievements of malaria elimination in Jiangsu Province.

摘要： 目的　分析2019年江苏省疟疾疫情，为制订防止疟疾输入再传播监测策略和措施提供科学依据。方法　收集2019年江苏省疟疾病例报告信息、流行病学个案调查、疫点调查与处置结案报告等疟疾疫情资料，并采用描述性方法进行分析。结果　2019年江苏省累计报告疟疾病例244例，均为实验室确诊的境外感染输入性病例，其中间日疟4例、恶性疟206例、三日疟12例、卵形疟22例；11例发展为重症病例，1例死亡。全省13个设区市报告病例数居前5位的依次为南京、南通、连云港、泰州、常州，报告的疟疾病例数占全省报告病例总数的59.84%。2019年报告的244例疟疾病例中，2例感染地为大洋洲巴布亚新几内亚、1例为亚洲巴基斯坦，其他241例均为非洲的27个国家或地区，其中输入来源较多的国家为安哥拉、刚果民主共和国、尼日利亚、赤道几内亚和科特迪瓦。244例疟疾病例中，在发病当天和发病后1～3 d就诊分别有77例（31.55%）和146例（59.84%），首次就诊和就诊后1～3 d确诊分别有149例（61.06%）和77例（31.55%），从就诊到确诊平均时间为（0.80 ± 1.59）d，较2018年的（1.34 ± 2.59）d显著缩短（U = 2.53，P < 0.05）。结论　江苏省应继续加强输入性疟疾监测和管理，提高输入性疟疾诊断能力和危重疟疾病例救治能力，以巩固消除疟疾成果。
