【摘要】 目的通过对2003~2012年流行性乙型脑炎(乙脑)病例进行分析,了解韶关地区乙脑的流行情况,为乙脑的预防控制提供科学依据。方法通过对疑似病例进行主动监测,回顾分析实验室确证病例相关资料。结果韶关市2003~2012年共报告乙脑病例47例,死亡2例,乙脑年发病率在(0~0.531)/10万。乙脑发病呈明显的季节性,主要集中在6~7月。47例乙脑病例中,6月发病20例,占42.55%;7月发病21例,占44.68%;6~7月病例占总病例数的87.23%。男性疑似病例130例,实验室确诊31例;女性疑似病例86例,实验室确诊16例;男性阳性病例多于女性。47例确诊为乙脑病例中,0~<4岁6例,4~<7岁22例,7~<20岁17例,20岁及以上2例,患者以学龄前儿童和学生为主(占82.97%)。乙脑病例中主要以无免疫史和免疫史不详为主(32例),占病例总数的68.08%;有免疫史的15例,占病例总数的31.92%。结论预防控制乙脑首先应该抓好乙脑疫苗的接种,建议每年在乙脑流行季节前开展乙脑疫苗的强化免疫,重点做好农村和城郊地区的防蚊灭蚊工作,同时加强实验室监测。更多还原
