Epidemiological characteristics of imported Plasmodium malariae and ovale malaria in Fujian,China,2008-2016

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。
