背景甲型肝炎病毒经输血途径传播至今尚无分子生物学证据。病例报道:一名33岁无症状的女性自愿者献了一次全血。13天后她被诊断为急性HAV感染。在回顾性研究中,应用定量逆转录PCR法(RT-PCR)在被隔离存放的、该献血者的新鲜冰冻血浆中检出高的病毒载量。而抗HAV IgM和IgG末被检出,丙氨酸转氨酶也未增高。她捐献的红细胞刚好在第14天 Background Hepatitis A virus is transmitted by the blood transfusion route There is no molecular biological evidence so far. Case Report: A 33-year-old asymptomatic female volunteer offered a whole blood. She was diagnosed with acute HAV infection after 13 days. In a retrospective study, a high viral load was detected in freshly frozen plasma of this blood donor using a quantitative reverse transcription PCR (RT-PCR) method in isolation. The anti-HAV IgM and IgG were detected, alanine aminotransferase was not increased. She donated red blood cells just on the 14th day
