Because there are more people in contact with the risk of being infected, even if you go to the airplane, train bathroom and other areas, you need to wear a good mask throughout to prevent the risk of possible aerosols. Although there is no one in the bathroom, if a suspected patient appears to cough before, his droplets may form aerosols. Even existing reports of feces and urine contain viruses that may form aerosols in a small space. Therefore, even if one goes to the toilet, one should wear a mask.
