摘要 广东省流行性乙型脑炎(乙脑)经过连续6年的低水平流行(发病率0.13/10万~0.19/10万)后,2003年发生局部地区的流行。为了解其流行病学特征,对当年乙脑监测资料进行了分析。结果显示:乙脑疫情波及全省21个市中的19个市,乙脑发病率0.50/10万,病死率7.81%。其中4个市的病例数占全省的68.49%(263/384)。6月为发病高峰,当月病例数占全年病例数的65.10%。乙脑病例中≤6岁占57.55%,7~9岁占29.43%,≥10岁占13.02%,与往年相比,2003年大年龄组病人比例有增高的趋势。无免疫史或免疫史不详者占乙脑病例的82.03%。为了控制乙脑流行,5~6月在流行地区开展乙脑灭活疫苗应急接种,在非流行地区开展乙脑疫苗的查漏补种,适龄儿童报告接种率达96.68%(5544481/5734659)。结果使全省乙脑流行时间缩短了1个月。为全面落实乙脑疫苗的预防接种,建议把乙脑疫苗纳入儿童计划免疫。 The epidemic Japanese B Encephalitis (JE) occurred in local area of Guangdong priovine after it's low epidemic for six years (incidence:0 13~0 19/100,000) The JE surveillance data was analyzed to know about it's epidemiological characters The results indicated the epidemic spreaded 19 cities of Guangdong province,incidence and fatality rate were 0.50/100,000 and 7.81% respectively.The cases in 4 cities were 68 49% (263/384) of the total cases June is the epidemic peak period,the cases in June were 65 10% of the total cases in the whole year The proportions of cases aged 6 years and younger, 7~9 years,10 years and older were 57 55%,29 43% and 13 02% respectively,comparing with those in the former years, in 2003 the proportion of elder cases had a upward trend The proportion of those cases no or no clear immunization history was 82 03% To control the JE epidemic,in May and June, the JE vaccine high-risk response vaccination was carried out in epidemic areas, and in other areas the unimmunized children were checked and provided JE vaccines Reported coverage among legal children was 96 68%(5,544,481/5,734,659) which made the epidemic period shortened for one month To put immunoprophylaxis of JE into effect,we suggested that JE vaccine should be incorporated into EPI in Guagngdong province
