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.
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.
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.
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.
分析2011年至2015年重庆市报告的境外输入性疟疾的流行病学特征，为完善输入性疟疾防控策略提供依据。
收集2011年至2015年重庆市境外输入性疟疾病例的流行病学资料，并对病例的病种、原发病国家、诊断与治疗情况进行描述性分析。
2011年至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%）；125例（84.46%）在非洲感染，其余23例（15.54%）在东南亚感染。患者以30至50岁男性务工人员为主，男女比例为11.42∶1。病例报告时间无明显季节性分布，但在6至8月和1至2月有两个小高峰。输入性疟疾病例从发病到就诊的中位间隔时间为1天，从就诊到确诊的中位间隔时间为2天。患者首选机构为县级医疗机构（50例，33.78%），其次为省级医疗机构（36例，24.325%）和个体医生（20例，13.51%），仅79例（53.38%）患者在首选机构确诊。142例（95.54%）病例得到规范治疗。43例（29.05%）患者出现严重并发症，3例患者死亡。
加强多部门协作，建立疟疾患者筛查协作调查机制，加强对境外务工人员的疟疾健康教育及基层医疗机构培训工作非常重要。
