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

一 | 1月15日，据外媒报道，英特尔计划发布一款高端桌面处理器i9-9990Xe，内部文件称，该处理器不是零售的，而是拍卖给原始设备制造商。    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.。据报道，这款新处理器将成为英特尔高端台式机系列中数量最高的处理器。目前的顶级处理器是I9-9980XE，18核36线程，基本频率为3.5GHz，提升频率为4.0GHz。根据Anandtech的说法，酷睿i9-9990Xe将是一个基本频率为4.0 GHz、提升频率为5.0 GHz的14核处理器。英特尔将处理器列为“非路线图产品”，这意味着它不会进入零售市场。英特尔不会直接向最终用户销售该产品，但会通过一系列拍卖（每季度举行一次）将其提供给选定的原始设备制造商，第一次拍卖定于2019年第三周进行。需要注意的是，该芯片具有255W的TDP，这意味着峰值功率将更高，适用于X299主板，Intel不提供任何保修。
