Let's talk to a medical journalist Cho Dong-chan.

Q. Is the European Corona 19 radio wave higher?

[Cho Dong-Chan/Medical journalist: Two months ago, a Chinese research team announced that a mutation called D614G occurs at the site where the corona19 virus comes into contact with the cell, and it becomes stronger in propagation. At the time, there was controversy in the academic world about whether it was really contagious, but after looking at it for two months, this seems to be true, and recently, a study showed that the propagation power is up to 6 times larger. But two days ago whether Nature is absolutely contradictory findings as to the differences in virulence of the virus it interpreted as a population, that is, the difference between people haetgeodeunyo nor silrigi seems to still watch some more.]

Over Q. drug, vaccine effectiveness varies?

[Cho Dong-chan/Medical journalist: Currently, the only remedy for corona19, remedyvir is not a method of acting on spike protein, but a principle of inhibiting specific enzymes. So, even if a mutation occurs in the spike protein, the effect will not change. There is a widespread view that vaccines will have similar effects and less effective. However, some of the treatments and vaccines currently being researched are being developed to work on spike proteins, so in this case, it may be necessary to redesign or reinforce them.] Q. Is'Summer

Mask' okay?

[Cho Dong-chan/Medical journalist: There are cases of airborne infections, but there are still more infections with droplets. It would be safe to wear a KF94 mask to block the possibility of airborne infections, but if the prevention measures are too demanding and difficult, there will always be people who do not keep them. Even in the public's living environment, even a splash-blocking mask is not perfect, but it can significantly reduce the risk of infection.]
