Wendy Zuckerman: 多年来,关于禽流感可能演变成全球大流行病的警报时断时续,这让人觉得有点像“狼来了”的故事。我想知道现在的情况是否真的发生了变化,是否有什么不同之处。 Blythe Terrell: 确实有一些事情使得情况变得更加严重。首先,家禽养殖场受到了严重的打击,美国正经历着有史以来最大规模的禽流感爆发,导致数百万只家禽死亡,鸡蛋价格也因此上涨。更重要的是,禽流感已经蔓延到450多种动物身上,联合国也称动物中的传播是“前所未有的”。我认为现在的情况非常严重,禽流感可能会彻底爆发,导致另一场全球大流行。 Seema Lakdawalla: 我认为禽流感对人类最大的威胁在于,它具有很高的致死率。虽然目前还没有出现人际传播的病例,但病毒一旦进入哺乳动物体内,就可能发生变异,从而更容易在人与人之间传播。尤其是在牛身上发现禽流感后,情况变得更加令人担忧,因为牛是家畜,人类与它们的接触非常频繁。此外,受污染的牛奶和粪便泻湖也增加了病毒传播的风险。我个人已经开始感到担忧,因为我们正在允许病毒每天进行数千次“射门”,这大大增加了病毒变异的可能性。
