| 8. | The continual circulation of avian influenza in birds and the close proximity of birds to human beings increase the chance of an unprotected individual being exposed to an infectious and potentially deadly agent . when people are concurrently infected with human and avian influenza virus strains , they may serve as the mixing vessel for the emergence of a novel subtype of virus having sufficient human influenza genes to facilitate transmission from person to person
禽流感在鸟类中持续散播，加上鸟类与人类的活动范围接近，令人类在无保护的情形下接触可致命传染媒介的机会大增若病者同时受人类流感病毒及禽流感病毒感染，就有可能成为病毒的混合炉，并由此产生具有足够人类流感基因易于在人与人之间传播的新品种病毒。 |
