新型コロナウイルスが変異したことで感染力が強まったことを確認したということです。
東京大学医科学研究所の河岡義裕教授は新型コロナウイルスが変異したことで感染力が強まったと発表しました。変異はD614Gと呼ばれ、ウイルスの表面にある突起部分で起きたもので、変異の前よりも細胞に結合しやすくなったということです。河岡教授はハムスターなどを使った実験で変異したウイルスが従来のウイルスよりも飛沫（ひまつ）感染しやすいことを確認しました。現在、世界で蔓延（まんえん）しているのはこの変異ウイルスですが、変異前のウイルスをもとに作ったワクチンも効果が期待されるとしています。
It was confirmed that the infectivity of the new coronavirus was strengthened by the mutation.
Professor Yoshihiro Kawaoka of the Institute of Medical Science, the University of Tokyo, announced that the mutation of the new coronavirus increased the infectivity. The mutation, called D614G, occurs in a protrusion on the surface of the virus (Spikes), which means that it is easier to bind to cells in humans than it was before the mutation. Professor Kawaoka confirmed in experiments using hamsters, hamsters with mutated version of viruses are more susceptible to droplet (himatsu) infection than hamsters with conventional viruses. Currently, it is this mutant virus that is widespread in the world, but it is expected that vaccines made based on the virus before mutation will also be effective.
