Air pollution causes harm and disasters to forests, rivers, oceans, animals and plants, causes great harm to human health, easily causes numerous diseases and harms the healthy development of the bodies of young children. Therefore, the mask is an indispensable protective tool in daily life.
Recently, the new coronavirus causes a large number of infections in the form of droplet transmission and contact transmission. With droplet propagation being the most dominant mode of propagation. When a human body is infected with such viruses, hundreds of millions of new virus particles are continuously produced in the body, particularly in the saliva of the patient and in secretions from the respiratory tract, such as the throat. When a patient coughs or sneezes, saliva and droplets wrapped with viruses are spread into the air, and people who are not properly protected around are easily infected. Studies have shown that the novel coronaviruses survive in air at the corresponding temperatures for periods of hours to days. Therefore, wearing the mask is the most effective way to protect against viruses and prevent the viruses from invading human body.
