目的 :了解部队 1999年入伍新兵TT病毒 (TTV)感染情况 ,为部队做好TTV感染的防治工作提供依据。方法 :采用巢式PCR方法 ,对驻闽南某部 2 51名 1999年入伍新兵血清进行TTV -DNA检测 ,同时做抗HAV -lgM、HBV -M、HCV -RNA、抗HEV -IgG和肝功能检查。对TTV感染者和肝功能异常者进行重点体检和流行病学调查。结果 :在 2 51名被检的新兵中 ,发现TTV感染者 19例 ( 7.5% ) ,其中福建、江西、江苏、山东和河南籍新兵分别为 4例 ( 8.0 0 % )、2例( 5.13% )、6例 ( 8.82 % )、6例 ( 7.89% )和 1例 ( 5.56% ) ;来自农村 10例新兵阳性感染率为 5.2 9%( 10 / 189)、城市为 14.5% ( 9/ 62 ,P <0 .0 5)。TTV感染者均无乏力、纳差、肝脾肿大等肝炎的症状体征。结论 :某部 1999年入伍新兵中存在TTV感染 ,均为健康携带者 ;TTV感染率五省籍新兵无显著差异 (P >0 .0 5) ,来自城市新兵显著高于农村新兵 (P <0 .0 5)。
Objective: To understand the status of troop troop infection (TTV) recruited in 1999 and provide basis for preventing and controlling TTV infection. Methods: The nested PCR method was used to detect TTV-DNA of 251 newly recruited serogroups from a certain ministry in southern Fujian province and to detect anti-HAV-lgM, HBV-M, HCV-RNA, anti-HEV-IgG and liver function . TTV infection and liver dysfunction were key physical examination and epidemiological investigation. Results: Twenty-five (7.5%) TTV-infected patients were found in the recruits recruited from TTV, among which recruits from Fujian, Jiangxi, Jiangsu, Shandong and Henan were found to be 4 cases (8.0%) and 2 cases (5.13% ), 6 cases (8.82%), 6 cases (7.89%) and 1 case (5.56%). The positive infection rates among 10 recruits from rural areas were 5.29% (10/199) and 14.5% P <0. 05). TTV infection were no fatigue, anorexia, hepatosplenomegaly and other symptoms and signs of hepatitis. CONCLUSION: TTV infection was found in a recruited army in 1999, all of whom were healthy carriers. There was no significant difference in the rate of TTV infection among recruits from five provinces (P> 0.05), recruits from urban areas were significantly higher than those from rural recruits (P <0) .0 5).
