Groups such as the University of Hong Kong have reported that patients who were infected with the usual "cold" coronavirus and put on commonly used disposable masks did not get out of the mask. The new coronavirus also shows that patients using masks may be able to slow the spread of infection.

Research groups at the University of Hong Kong and others collaborated with patients infected with the cold-causing coronavirus and published the results of a study in a medical magazine Nature Medicine on March 3 to see if a common disposable mask could prevent the virus. Did.

The research group used a special device capable of detecting the virus to examine the virus that escaped through breathing and coughing in 30 minutes. Three out of 10 patients without masks were flying more than 5/1000 mm. The virus was detected in the eyelashes, but not in all 11 masked patients.

It also means that no virus was detected in the masked patient, even in a flight that floated in smaller air.

The research group said that some patients did not cough, so the research group released the virus even if it did not show symptoms, but even if the patient wears a mask even with the new coronavirus, the speed of infection spreads. To show the potential for
