TED-Ed: 終結病毒的三種方式

終結病毒的三種方式

在野生世界中，病毒是非常成功的有機體。在地球上，病毒顆粒的數目是宇宙中可觀察到的星星的數目乘以一億倍。就算如此，病毒仍然有可能／確實會絕種。所以，造成新冠肺炎的病毒絕種的可能性如何？這支影片會探討病毒可能會被迫絕種的三種方式。

Viruses are astonishingly abundant, with around 100 million times more virus particles on Earth than there are stars in the observable universe. Still, entire viral species can be wiped out through three main routes: exhausting all hosts, effective vaccination, or being outcompeted by a stronger variant. The near-extinction of the B/Yamagata flu and the dramatic rabbit die-off from myxoma virus show how unpredictable these routes can be. While SARS-CoV-2 is now deeply rooted in humans and animals, its fate could change if a universal vaccine is developed.
