【摘要】：目的分析貴州省2011-2015年流行性乙型腦炎(乙腦)的流行病學(xué)特征,為乙腦防控提供科學(xué)依據(jù)。方法采用描述性流行病學(xué)分析方法,對(duì)貴州省2011-2015年乙腦發(fā)病數(shù)據(jù)資料進(jìn)行分析。結(jié)果貴州省2011-2015年乙腦年平均報(bào)告發(fā)病率0.3355/10萬(wàn),年發(fā)病率呈逐年下降趨勢(shì);病例高度散發(fā),覆蓋范圍逐年縮小,相對(duì)集中在貴州省的西部和西南部地區(qū);乙腦發(fā)病季節(jié)性明顯,8月達(dá)到高峰;仍以小年齡兒童發(fā)病為主,15歲以下兒童占90%以上,但8月齡~5歲組病例所占比例呈逐年下降趨勢(shì),≥15歲組病例構(gòu)成比呈逐年上升趨勢(shì);職業(yè)分布以散居兒童(58.12%)和學(xué)生(34.19%)為主;乙腦病例中有免疫史的比例呈上升趨勢(shì)。結(jié)論貴州省2011-2015年乙腦防控效果明顯;乙腦病例分布具有一定區(qū)域性,發(fā)病年齡以小年齡兒童為主,但出現(xiàn)年齡后移趨勢(shì)。應(yīng)進(jìn)一步采取以接種乙腦疫苗為主的綜合性防控措施;結(jié)合各地監(jiān)測(cè)情況,針對(duì)高發(fā)地區(qū)和重點(diǎn)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. Results the average reported incidence of je in Guizhou Province from 2011 to 2015 was 0.3355 / 100 000. The annual incidence is decreasing year by year. The cases were highly distributed and the coverage was reduced year by year, which was relatively concentrated in the western and southwest areas of Guizhou Province. The incidence of encephalitis B was seasonal and reached its peak in August. The incidence rate of children under 15 years old was more than 90%, but the proportion of patients with age of 8 months and 5 years of age was decreasing year by year, and the proportion of cases with age 鈮，
