美国新冠病毒领先中国2代：XBB爆发式突袭 (而且一直在变异中)

dalap

昨天是2022年12月24日，西方传统的圣诞前夜。美国疾控中心CDC公布了最新的新冠毒株分布图，大家可以清楚的看到：

BA.5、BF.7毒株已经彻底退场，BQ.1.1和BQ.1已经达峰，XBB一支崛起！

而目前中国疫情爆发的主要毒株是BA.5.2和BF.7，美国的毒株进化比国内毒株要领先2代。

我们先看之前被媒体炒作的“地狱犬杀疯了”的BQ.1.1毒株，目前已经达峰：

上周BQ1.1的比例是35.5%,本周为35.7，没有继续出现明显的增加。

Omicron BQ, XBB subvariants are a serious threat to boosters and knock out antibody treatments, study finds
PUBLISHED WED, DEC 14 2022




Scientists, in a study published online in the journal Cell, found that the BQ and XBB subvariants are “barely susceptible to neutralization” by the vaccines, including the new omicron boosters.

This could result in a surge of breakthrough infections and reinfections, though the vaccines have been shown to hold up against severe disease, they wrote.

Key antibody drugs, Evusheld and bebtelovimab, were “completely inactive” against the new subvariants, according to the study.


The omicron subvariants that have become dominant in recent months present a serious threat to the effectiveness of the new boosters, render antibody treatments ineffective and could cause a surge of breakthrough infections, according to a new study.

The BQ.1, BQ.1.1, XBB and XBB.1 omicron subvariants are the most immune evasive variants of Covid-19 to date, according to scientists affiliated with Columbia University and the University of Michigan. These variants, taken together, are currently causing 72% of new infections in the U.S., according to data from the Centers for Disease Control and Prevention.

澳大利亚散播得好快

Australia recorded 31,636 new cases of Covid last week — marking a 2.2 per cent increase.

Health authorities reported 21 cases of the XBB variant in NSW in the week ending October 15, while cases in Victoria rose by 24.7 per cent to 8537 in the week ending October 28.

The state’s hospitalisation rate rose 20.3 per cent to 172 patients, with seven people on average dying with the virus each day.

“Surveillance shows the presence of multiple Omicron subvariants in Victoria including rapid growth of (the Omicron subvariant) BQ. 1 and XBB in the past month, with a combined prevalence of approximately 10 per cent in wastewater and clinical sample,” Victoria’s chief health officer Professor Brett Sutton said.

“Continued growth at these rates would see these subvariants overtake BA. 5 as the dominant varian.”

XBB异军突起，成为所有毒株中唯一大幅增加的：

从上周的11.2%增加到本周的18.3%，增幅高达50%！

4周前，也就是2022年11月26日，XBB毒株的比例也仅有2.7%；仅仅一个月时间，XBB毒株的比例增加了6倍！按照这个趋势，XBB在未来2-3周就会成为美国主导性的毒株。
