【摘要】：目的分析贵州省2011-2015年流行性乙型脑炎(乙脑)的流行病学特征,为乙脑防控提供科学依据。方法采用描述性流行病学分析方法,对贵州省2011-2015年乙脑发病数据资料进行分析。结果贵州省2011-2015年乙脑年平均报告发病率0.3355/10万,年发病率呈逐年下降趋势;病例高度散发,覆盖范围逐年缩小,相对集中在贵州省的西部和西南部地区;乙脑发病季节性明显,8月达到高峰;仍以小年龄儿童发病为主,15岁以下儿童占90%以上,但8月龄~5岁组病例所占比例呈逐年下降趋势,≥15岁组病例构成比呈逐年上升趋势;职业分布以散居儿童(58.12%)和学生(34.19%)为主;乙脑病例中有免疫史的比例呈上升趋势。结论贵州省2011-2015年乙脑防控效果明显;乙脑病例分布具有一定区域性,发病年龄以小年龄儿童为主,但出现年龄后移趋势。应进一步采取以接种乙脑疫苗为主的综合性防控措施;结合各地监测情况,针对高发地区和重点人群制定有效的防控策略。
[Abstract]:Objective to analyze the epidemiological characteristics of epidemic encephalitis B (je) in Guizhou province from 2011 to 2015, and to provide scientific basis for the prevention and control of encephalitis B. Methods descriptive epidemiological analysis was used. The data of Japanese encephalitis B (je) incidence in Guizhou province from 2011 to 2015 were analyzed.
