New COVID Sub-Variant BA 2.75 Detected in India, WHO Says_我的网站

一 |     The World Health Organization (WHO) has revealed that the new BA.2.75 sub-lineage of the Omicron variant of COVID has been detected in India.,"In Europe and America, BA.4 and BA.5 are driving waves. In countries like India, a new sub-lineage of BA.2.75 has also been detected, which we're following," WHO Director-General Tedros Adhanom Ghebreyesus said at a press briefing on Wednesday.,He said that new COVID cases reported worldwide have spiked by nearly 30 percent.,Experts say the BA.2.75 variant includes new mutations in the spike protein, in addition to mutations that are already present in the Omicron variant.,This allows it to evade several antibodies and can infect people who have been vaccinated or infected previously. The detection of BA.2.75 has led scientists across the globe to dive deep into the research to learn more about the new variant and the possibility of another COVID wave.,In India, the BA.5 sub-variant has been detected in the states of Tamil Nadu, Karnataka, West Bengal, Maharashtra, Telangana, Delhi, Haryana, Gujarat, and the Ladakh union territory as well.,WHO Chief Scientist Soumya Swaminathan said in a video posted on Twitter that there has been an emergence of a sub-variant called the BA.2.75, "first reported from India and then from about 10 other countries.",Swaminathan said there are still limited sequences available of the sub-variant to analyze, "but this sub-variant seems to have a few mutations on the receptor-binding domain of the spike protein. So obviously, that's a key part of the virus that attaches itself to the human receptor.","So we have to watch that. It's still too early to know if this sub-variant has properties of additional immune evasion or indeed of being more clinically severe. We don't know that," she added.,Last week, Dr. Shay Fleishon, an Israeli scientist, claimed that a new coronavirus variant had hit 10 Indian states and sparked concerns of a fourth wave of the COVID-19 pandemic.,The current daily positive test rate is, however, is around 4.32 percent, down from around 16-17 percent in January 2022, the peak of the first Omicron wave.。    　　美国总统特朗普当地时间8月21日对媒体表示，他本周并未指示美国财长贝森特干预债券市场。在被问及“面对美国长期债券收益率再回升还有什么干预手段”时，特朗普称，“终极干预手段是美军，如果需要，将出动美军”。

二 | 　　对于特朗普将“美军”和“美债”这看似八竿子打不着的二者关联起来的说法，有网友评论称，“特朗普的意思是，只要他挑起一场真正的全面战争，就能逼出个‘避险买盘’，好给美债接盘。”对此有网友指出，“谁要避险去买这样一个国家的国债？它正靠发动毫无意义的战争来宣泄，却连支撑战事的工业产能都没有，还日渐暴露出政治与财政的双重溃烂。”还有网友调侃称，“美国这是想直接占领头号持债国日本，然后把欠他们的债一笔勾销吗？逻辑满分啊！”　　美国财政部日前罕见加大对长期国债市场的干预力度。贝森特当地时间8月20日称，可能进一步扩大长期国债回购规模。此前，财政部刚刚宣布将把回购规模“至少扩大一倍”。这被视为美国政府对长期债券收益率持续处于高位的“救市”之举。不过目前，贝森特声明带来的收益率下行已基本回吐。　　相关报道　　特朗普重磅发声：未指示贝森特干预美国债市 经济增长将自行化解债务问题　　针对近期美国国债市场掀起的抛售潮，美国总统特朗普当地时间21日表示，没有指示财政部长贝森特干预美国债券市场，是贝森特自行决定采取行动，并称美国经济增长将自行化解国债问题。

四 | 　　特朗普说，“我们对霍尔木兹海峡周边整个地区，包括其腹地和陆地区域，拥有完全的控制权。所以，他们很希望达成协议，但在我看来，他们还没准备好达成合适的协议。”　　当被问及美国对伊朗的军事选择是否有限时，特朗普表示：“这只是意味着我们正在观望事态发展。”　　此前，美国副总统万斯在20日播出的一档节目中称，美国与伊朗战事“进入新阶段”，对伊朗施加经济压力是“最有效手段”，但这是一种“微妙的博弈”。万斯针对“微妙的博弈”解释道：“因为我们向他们（伊朗）施加经济压力，他们也会试图向我们施加经济压力。”他同时补充说：“但过去几周的事实是，他们感受到的压力远大于我们。”（文章来源：CCTV国际时讯）。
