Results of malaria surveillance in Guangxi area of Guangdong, Guangxi and Hainan malaria joint management in 2013

目的分析2013年粤桂琼疟疾联防广西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2013年广西区8市县疟疾监测数据并进行统计、分析。结果 2013年广西区8个市县报告疟疾病例31例,占全广西全年总病例数的2.48%（31/1251）;8市县人群发病率为3.7/10万。流动人口血检阳性率为0.48%,其中间日疟4例,恶性疟25例,三日疟和混合感染各1例;来自非洲感染病例29例,东南亚地区感染病例2例;有67.74%疟疾病例集中出现在6~7月份,2013年8市县报告的31例疟疾病例与2012年报告的16例疟疾病例相比,疟疾病例数上升了93.75%,8市县与全广西一样全年无输入性疟疾继发病例及死亡病例发生。结论 2013年三省（区）疟疾联防区广西的8个市县流动人口疟疾病例与2013年广西全省疟疾病例急速上升一样,疟疾病例数明显增加,流动人口疟疾监测仍需加强。

Objective To analyze the incidence and prevalent trend of malaria in Guangxi area of Guangdong, Guangxiand Hainan malaria joint management in 2013, and provide the basis for working out preventive measures.

The positive rate of blood test was 0.48% in floating population. The reportedmalaria cases included 4 Plasmodium vivax malaria cases,25 Plasmodium falciparum malaria cases, 1 mixed infection and 1Plasmodium malariae malaria case.
