人甲型和B型流感病毒的流行病学。在过去的世纪中,已经在人类中鉴定了三种不同的甲型流感病毒血凝素亚型(H1、H2和H3)和两种神经氨酸酶亚型(N1和N2)。虽然没有活的1918年病毒(实心正方形)可用,但已通过RT-PCR对1918名受害者的福尔马林固定或冷冻组织样本中的病毒RNA进行了测序(35)。拯救含有重建的1918基因的病毒可以研究这种早已消失的毒株的毒力特征(36)。
Epidemiology of human influenza A and B viruses. Three different influenza A virus hemagglutinin subtypes (H1, H2, and H3) and two neuraminidase subtypes (N1 and N2) have been identified in humans over the last century. Although no live 1918 virus (solid square) is available, viral RNAs have been sequenced following RT-PCR from formalin-fixed or frozen tissue samples of 1918 victims (35). Rescue of virus containing reconstructed 1918 genes allows study of virulence characteristics of this long-gone strain (36).
