2011年粤桂琼三省(区)疟疾联防区疟疾疫情分析

Analysis on malaria epidemic of Joint Malaria Prevention District in Guangdong, Guangxi and Hainan Provinces in 2011

目的分析2011年粤桂琼三省(区)流动人口疟疾联合管理区疟疾发病情况及流行态势,为制定防治措施提供依据。方法收集联防区33个市县2011年疟疾监测数据并进行统计、分析。结果 2011年粤桂琼三省(区)33个市县共报告疟疾病例122例,发病率为0.22/10万,与2010年(0.19/10万)比较,发病率上升了15.79%,其中本地病例2例,比2010年(26例)减少了92.31%;流动人口病例120例,比2010年(61例)增加了96.72%。结论 2011年三省(区)疟疾发病率继续维持在较低水平,广东、广西流动人口疟疾病例增加是三省联防区疟疾发病率升高的主要原因,进一步加强对外出到非洲和东南亚国家务工人员外出前的健康教育和返乡后疟疾监测力度是巩固疟防成果的关键。

Objective To analyze the malaria incidence and epidemic trend of the Joint Malaria Prevention District（JMPD） of Guangdong,Guangxi and Hainan provinces,so as to provide basis for the development of prevention measures.Methods The malaria surveillance data of the Joint Malaria Prevention District from 33 cities and counties were collected and statistically analyzed.Results A total of 122 malaria cases in 2011 of 33 cities and counties in Guangdong,Guangxi and Hainan provinces were reported.The incidence rate was 0.22/100 000,and increased by 15.79% compared with 2010（0.19/100 000） including 2 local cases.It decreased by 92.31% compared with 2010（26 cases）.There were 120 cases of the floating population which increased by 96.72% compared to 2010（61 cases）.Conclusions The incidence of malaria continues to be at a low level of three provinces in 2011 and the malaria incidence increased mainly due to the increase of malaria cases of the floating population from Guangdong and Guangxi.To further strengthen the health education on workers who work in Africa and Southeast Asia before going abroad and the malaria surveillance efforts after returning home are key points to consolidate the results of malaria control.
