L V.s S type.
샘플에 L이 더 많이 나타나는데, 중국 우한에서 S가 처음 보였지만 나중에 L도 많았습니다. 지금 어디에 뭐가 더 많고 적은지는 샘플도 없고 분석도 안되어 아무도 모릅니다. 따라서 전염성이 4배 큰지도 알 수 없고요.
The differences between the two identified strains are tiny. In fact, they can’t really be considered to be separate “strains”, says Jones. And many of the genetic differences won’t affect the production of proteins, and so won’t change the way the virus works, or the symptoms it causes, he says. One is not more deadly than the other.
“In all practical terms, the virus is as it was when it originally emerged,” says Jones. “There’s no evidence it is getting any worse.” The sentiment is echoed by the World Health Organization. The study by Tang and colleagues only suggests there is some genetic diversity of the virus – it doesn’t mean it is changing, a representative told New Scientist.
