Special Mask for the Nose: Scientists Create Strange Anti-Coronavirus Mask

In Mexico, scientists have developed a mask designed to enhance protection against the coronavirus. The distinctive feature of this invention is that it can be worn solely over the nose. This was reported on the website of the Mexican government.

The mask has been created to strengthen the body's defense against the virus when an individual removes a regular mask that covers the face. This situation may occur, for instance, during a dental visit or while eating.
