オミクロン変異種の安心材料 Some Relief on Omicron Variant

 オミクロン変異種の安心材料 Some Relief on Omicron Variant

Above Fig is saying that lots of mutations were found around spike proteins

オミクロン株が出てきて、世界は大騒ぎだ。感染力がデルタ株と比べても絶大らしい。Omicron Variant emerged and world is in confusion. It looks far more infectious than Delta Variant.

ただ、変異した場所はスパイクたんぱく質だけのようで、重症化率は変わらない気がする。However, mutated parts are only on spike proteins, hence I believe fatality did not change.

スパイクたんぱく質そのものが血管を攻撃し血栓を作るようなので、変異がスパイクたんぱく質部分だけといっても一概に侮れないが、ただ、一般的には、感染力が増大すると、毒性は弱まるらしい。Nevertheless spike protein itself attacks veins to create clot, so we should not underestimate the impact although mutated parts are only on spike protein. However, generally speaking, the more infectious, the less fatal virus will be. 

現状、デルタ株は依然猛威を振るっている。Currently Delta variant is still going around the world with serious damage. 

オミクロンにより感染力が増した分だけ、感染者数は増大するだろうが、重症化が防げていれば、大勢に影響はないのではと考えられる。As more infectious Omicron variant mutated, the more infection number we will see however, as long as mortality remains unchanged, actual impact should be minimal.
