The effectiveness of the medical mask 50%

Japanese researchers have proven that masks can protect from corona virus particles spread in the air, but even the finest types cannot completely stop the risk of transmission.

And the Japanese newspaper Japan Times reported that scientists at the University of Tokyo built an isolated room and put in it statues faces facing each other, one of which is equipped with a spray that simulates a cough and spreads real particles of the Corona virus, while the rest of the heads simulate the natural breathing process while the virus is flying in the air.

The researchers found that the cotton muzzle limited the inhalation of the virus by 40%, while the medical muzzle “N 95” limited it by 90%, but even with the medical mask tightly placed on the face of the statue, particles of the virus leaked through it.

And when I put a muzzle, whether cotton or medical, on the face of the statue that spreads the disease, it limited the spread of the virus by 50%.
