2005—2014年福建南平市输入性疟疾疫情分析

Epidemic analysis of imported malaria during 2005-2014 in Nanping,Fujian

目的通过对福建省南平市2005--2014年疟疾疫情监测分析，研究其流行特征，为消除疟疾后监测工作提供依据。方法对2005--2014年南平市输入性疟疾病例按年份、季节、地区、职业、感染来源、病例类型、诊治情况等进行分析。结果2005-2014年南平市共报告疟疾病例71例．均为输入性病例．其中非洲占63-38％，东南亚占25．35％，国内其他地区占11．26％；前6年输入性疟疾疫情稳定，每年3～5例；后4年输入性疟疾疫情明显上升，每年9～17例，差异显著；由非洲输入的疟疾后4年（39例）与前6年（6例）比病例数呈明显上升，而由国内其他地区输入的后4年（1例）比前6年（7例）则明显下降：输入性疟疾疫情上升主要是由于前往非洲的出国务工人员大量回国引起，病例主要集中在出国务工人员较多的延平区（28例，占39．43％）的炉下镇（8例）、黄墩社区（5例）、四鹤社区（4例）和建瓯市（23例，占32．39％）的瓯宁街道（10例）、建安街道（4例）。结论南平市近几年输入性疟疾疫情明显上升，主要是由于前往非洲的出国务工人员大量回国引起．今后应加强对劳务输出归国人员的疟疾防治管理工作。

Objective The epidemic characteristics of malaria was investigated through analysis on malaria monitoring data from 2005 to 2014 in Nanping, Fujian so as to support the post-elimination monitoring on malaria. Methods The malaria epidemic data and all case reports from 2005 to 2014 were collected and analyzed for their epidemic characteristics. Results A total of 71 malaria cases was reported from 2005 to 2014 and all of them were imported cases. Among them, 63.38% was from Africa, 25.35% from Southeast Asi- a, and 11.26% from other domestic areas. The most of malaria patients were migrant workers who were infected abroad and the cases were dramatically increased since 2010 due to a significant return of migrant workers from African countries. At the mean time, domestic malaria cases were significantly decreased. These imported cases were concentrated on villages and towns where there were more migrant workers going abroad. Cases fo- cused on the regions where many people went to Africa for jobs, such as Luxia Town （8 cases）, Huangdun Community （5 cases）, Sihe Community （4 cases） in Yanping area （28 cases, 39.43%） and Street Ouning, Street Jian＇an in Jianou city （23 cases, 32.39%）. Conclusion There is an increasing challenge to prevent and control the imported malaria epidemics carried by migrant workers in Nanping City. It is necessary to reinforce the moni- toring and management of imported malaria cases, especially focusing on migrant workers from African countries.
