Background and objective : the hong kong incidents that avian influenza viruses h5n1 and h9n2 can infect humans without any intermediate mammal host in 1997 and 1999 respectively remind us that the next influenza pandemic is imminent
背景和目的： 1997 ， 1999香港發生的禽流感h5n1 ， h9n2直接感染人的報道提醒我們：人類大流感的流行已為之不遠了。 -
Avian influenza is transmitted from infected live birds to humans. although human - to - human transmission is inefficient, all influenza viruses have the ability to change genetically, and scientists are concerned that the h5n1 virus could one day be able to spread easily from one person to another. because the virus does not commonly infect humans, there is little or no immune protection against it in the human population. if the h5n1 virus could spread easily from person to person, an influenza pandemic could occur
禽流感可以從活鳥身上感染人類，現時人傳人的效率雖然不大，但所有流感病毒都有出現基因變異的能力，因此科學家都很關注h5n1病毒終有一天會輕易地在人與人之間傳播；而且因為這種病毒感染在人類身上並不常見，人體抵抗這種病毒的免疫力極低，甚至根本沒有免疫力，一旦病毒能夠輕易地在人與人之間傳播，就會出現一場流感大流行。 -
