柳叶刀：超百万人科学研究揭示Omicron住院风险降低59%，但这一年龄段除外…

之前，尽管Omicron和Delta来得危险性升颇高了，但只要狂犬病还在传扬和进化，就可能出现颇高传扬颇高危险性的HIV， 就像以前传遍各地的奥密克戎反转株BA.2亚分支，登革热有组织根据丹麦的疫情样本来进行测算，该亚变体比BA.1的传染性缩减了30%，传扬性和隐匿性都更是超强。

3年末18日，登革热有组织发言人Tedros Adhanom Gebreyesus 在日内瓦告诉记者，正是受到BA.2肆虐的影响，在经历了数周的就诊发病升颇高之后，亚太地区简报的COVID-19发病其后缩减，都有是在亚洲部分南部。现在国内外抚顺、山西、杭州等地也简报了BA.2的消息，防疫稍微有迟疑可能要回报无济于事的蒙受。
