摘　　要：[目的]为调查乙脑的危害和流行因素,于2005年对贵州发病较多的务川县进行调查。[方法]对务川县疾控中心1998年以来的乙脑疫情资料和乙脑疫苗接种情况等进行调查,并采用1:4病例对照的方法对蚊香、蚊帐使用情况与乙脑的发病关系等进行调查,并采对照组的血清查乙脑IgG抗体。[结果]从疫情来看,2004年发病率有明显下降,但是2005年又有所上升,原因可能是2003年和2004年两年曾经接种过乙脑疫苗,而2005年没有接种乙脑疫苗。病例对照方法未找出其他相对危险因素。[结论]接种疫苗可能是有效预防乙脑的方法。务川县乙脑的发病率高,死亡率较高,乙脑病例的致残情况重及疾病负担重,说明了乙脑对儿童健康的危害、对社会和家庭的负担和预防控制乙脑的重要意义。[Objective]To investigate the harm and risk factors of encephalitis B in Wuchuan County in Guizhou Province.[Methods]The reports of epidemic situation of encephalitis B since 1998 and the incubation situation of Encephalitis B Vaccine were reviewed and studied.And 1：4 case-control study was conducted to explore the relationship between the using situation of mosquito net or mosquito-repellent incense and the incidence of encephalitis B.Besides,the sera of the controls were collected to detect the IgG antibody.[Results]The incidence rate of encephalitis B decreased obviously in 2004 and then increased again in 2005.The main reasons were likely to inoculation with Encephalitis B Vaccine for local children in 2004 and without encephalitis B Vaccine inoculation in 2005.No risk or protective factors were found in the case-control study.[Conclusions]Inoculation with Encephalitis B Vaccine may be the effective method of preventing the incidence of encephalitis B.Investigators find that encephalitis B is harmful to children,and encephalitis B patients bring heavy burden to their families and the whole society,therefore it is important to prevent encephalitis B epidemic.
