2005-2014年江苏省疟疾疫情分析

Analysis of epidemic situation of malaria in Jiangsu Province from 2005 to 2014

目的 分析2005-2014年江苏省疟疾疫情及流行特征,为制订和调整全省疟疾消除策略和措施提供依据。方法 收集2005-2014年江苏省疟疾疫情数据资料,对疟疾发病情况、感染来源以及病例的时间、地区和人群分布进行分析。结果 2005-2014年,江苏省共报告疟疾病例5 069例,其中间日疟3 422例（67.51%）、恶性疟1 497例（29.53%）、未分型150例（2.96%）;本地感染疟疾病例2 139例（42.20%）、国内输入病例1 131例（22.31%）、境外输入病例1 799例（35.49%）;男性病例3 809例,女性1 260例,男女性别比为3.02∶1。病例年龄以25~60岁为主,占67.15%;职业以农民和民工为主,分别占40.26%和23.63%。60.58%的病例分布于徐州、宿迁、淮安、苏州市和南通市。2005-2009年病例以间日疟为主,自2010年起以恶性疟为主,且主要为境外输入性感染,从2012年起无本地感染病例。结论 江苏省本地感染疟疾疫情已得到有效控制,初步实现消除疟疾目标。但境外输入性疟疾病例仍较多,且感染呈多样性,是目前的防控重点。

Objective To understand the epidemic situation and epidemiological characteristics of malaria in Jiangsu Prov-ince from 2005 to 2014,so as to provide the evidence for formulating and adjusting the strategies and measures on malaria elimi-nation in this province. Method The epidemiological data of malaria in Jiangsu province from 2005 to 2014 were collected, and the prevalence situation,infection sources as well as the temporal,regional and population distribution of the cases were an-alyzed. Result A total of 5 069 malaria cases were reported in Jiangsu Province form 2005 to 2014,there were 3 422 cases （67.51%）of vivax malaria,1 497 cases（29.53%）of falciparum malaria,and 150 cases（2.96%）that were unclassified. Among all the reported cases,2 139（42.20%）were local cases,1 131 were（22.31%）imported cases from other places in Chi-na ,and 1 799（35.49%）were imported cases from abroad. There were 3 809 male cases and 1 260 female cases,with a sex ratio of 3.02∶1. The patients were mainly aged from 25 to〈60 years（accounting for 67.15%）,and were mainly young adult farmers （40.26%）and migrant workers（23.63%）,who mainly distributed（accounting for 60.58%）in Xuzhou,Suqian,Huai’an,Su-zhou and Nantong cities. The predominant malaria type from 2005 to 2009 were vivax malaria,while after 2010,it changed to falciparum malaria. Conclusions The malaria epidemic situation has been effectively controlled in Jiangsu Province,which re-flects the initiative achievements of malaria elimination. However,there are still many imported malaria cases from abroad,and the species of the Plasmodium are diverse. Therefore,the imported malaria from abroad still remains the key of malaria control in Jiangsu Province.
