摘要
目的分析福建省输入性三日疟和卵形疟的流行特征,为制定防制对策提供依据。方法 2008—2016年,福建省疾病预防控制中心疟疾实验室诊断各类疟疾535例,用PCR基因诊断法确诊输入性三日疟和卵形疟共57例,收集其个案调查资料,回顾性分析其流行特征。结果 2008—2016年确诊的57例三日疟和卵形疟中,三日疟15例,病例虽少,但每年可见;卵形疟42例,除2016年外病例数呈上升趋势。二者主要以非洲输入为主(55例),尤其西非;除非洲外,仅从东南亚缅甸输入三日疟和卵形疟各1例。结论福建省输入性三日疟和卵形疟的增多,外出人口前往不同类型的疟疾流行区会变化,应引起重视。应掌握被忽视的三日疟和卵形疟的流行分布趋势,针对性地加强宣传教育,提高实验诊断能力。
Objective To analyze the epidemiological characteristics of imported Plasmodium malariae and Ovale malaria in Fujian for the disease control and prevention.Methods Totally 535 diagnosed malaria cases were collected in malaria laboratory of Fujian CDC from 2008 to 2016,and 57 cases of Plasmodium malariae and Ovale malaria were confirmed by using PCR method,and the data of case investigation were collected for analyzing the epidemiological characteristics.Results Among the 57 cases,15 cases for Plasmodium malariae,they were not so many cases,but the cases occurred every year.And the 42 cases of Ovale malaria,the cases were in an increasing tendency except2016.Both Plasmodium malariae and Ovale malaria cases were almost from Africa(55 cases),especially from west Africa.Besides Africa,only one Plasmodium malariae case and one Ovale malaria case were from Burma in Southeast Asia.Conclusion The following situation should be noticed seriously:the increasing tendency of imported malaria cases in Fujian,and the changing of people's going to different endemic areas of malaria.It is necessary to know the tendency of epidemiological distribution of these neglected malaria,and the health education and the ability of laboratory diagnosis should be strengthen.
