Why is this new H1N1 virus sometimes called “swine flu”?
This virus was originally referred to as “swine flu” because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs in North America. But further study has shown that this new virus is very different from what normally circulates in North American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and Asia and avian genes and human genes. Scientists call this a “quadruple reassortant” virus.
这种病毒最初是被称为“猪流感” ,因为实验室测试表明,这一新的病毒的许多基因与通常发生在北美的猪身上的非常类似的流感病毒,。
不过更多的研究显示,这个新的病毒与北美猪的病毒非常不一样。他有2个欧洲和亚洲禽流感的基因以及人类的基因。科学界称这个为“quadruple reassortant”病毒
本文解释了H1N1病毒最初被称为“猪流感”的原因:实验室测试显示其许多基因与北美的猪流感病毒相似。但进一步研究表明,该病毒包含来自欧洲和亚洲猪流感病毒的基因以及人类基因,因此被科学家称为“四重组”病毒。
