Abstract: Objective To analyze the epidemiological characteristics of overseas imported malaria reported in Chongqing City from 2011 to 2015, so as to provide the evidence for improving the imported malaria control strategies. Methods The epidemiological data of overseas imported malaria cases were collected and analyzed descriptively for the species, original countries, diagnosis and treatment in Chongqing City from 2011 to 2015. Results A total of 148 overseas imported malaria cases were reported in Chongqing City from 2011 to 2015, in which 96 (65.54%) cases were falciparum malaria, and 37 (24.32%) cases were vivax malaria; 125 (84.46%) cases were infected in Africa, and the rest of 23 (15.54%) cases were infected in Southeast Asia. Most of the patients were 30 to 50 years old male workmen, and the ratio of male to female was 11.42∶1. There was no obvious seasonal distribution among the reported timelines of the cases; however, there were two small peaks from June to August and from January to February. The median interval time of imported malaria cases from malaria onset to see a doctor was 1 day and from seeing the doctor to get malaria diagnosis was 2 days. The patients’ first selected institutions were county medical institutions (50 cases, 33.78%), then provincial medical institutions (36 cases, 24.325%) and private doctors (20 cases, 13.51%), and only 79 (53.38%) patients got malaria diagnoses in their first selected institutions. The standard treatment were provided to 142 (95.54%) cases. There were 43 (29.05%) patients had serious complications and three patients were dead. Conclusion It is very important to enhance the multi?sector’s collaboration to establish the collaborative investigation mechanism for screening malaria patients, and strengthen malaria health education for overseas workers and training courses in primary care medical institutions.

摘要: 目的 分析重庆市境外输入性疟疾病例特点,为输入性疟疾防控策略调整提供依据。 方法 收集2011-2015年重庆市报告的境外输入性疟疾病例流行病学资料,对其虫种、感染地、就诊情况、诊断结果和治疗情况等数据进行描述性分析。 结果 2011-2015年重庆市共报告境外输入性疟疾病例148例,其中恶性疟96例(65.54%),间日疟37例(24.32%);非洲国家输入125例(84.46%),东南亚国家输入23例(15.54%)。发病人群主要为30 ~ 50岁境外务工的男性工人,男女性别比11.42∶1。病例报告时间无明显季节变化,仅在年中(6-8月)和年初(1-2月)略有集中。从发病到就诊时间中位数为1 d,从就诊到确诊时间中位数为2 d。首诊单位主要集中在县级(50例,33.78%)、省级医疗机构(36例,24.32%)和个体医生(20例,13.51%),78例(52.70%)病例首诊为疟疾。病例规范治疗率95.54%(142/148),有43例(29.05%)出现了较严重的并发症,死亡3例。 结论 加强多部门合作,建立协查、主动筛查机制,针对境外务工人员开展疟疾防治健康教育,强化基层医疗机构的疟疾防治技术培训,提高首诊医疗机构的疟疾防治意识,是保证输入性疟疾病例规范管理和消除疟疾的重要措施。
