The importance of masks
Masks have a certain filtering effect on the air entering the lungs. When respiratory infections are prevalent, wearing masks has a very good effect when working in a polluted environment such as dust.
The main routes of transmission of new coronaviruses are respiratory droplets and contact transmission. Aerosol and fecal-oral routes of transmission need to be further clarified. Epidemiological investigations have shown that cases can be traced to close contact with confirmed cases.
Refers to the infection caused by the patient's sneezing, coughing, talking droplets, and exhaled gas directly inhaled;
It means that the droplets are mixed in the air to form an aerosol, which causes infection after inhalation;
It means that the droplets are deposited on the surface of the article, contact the contaminated hands, and then contact the mucous membranes of the oral cavity, nasal cavity, eyes, etc., causing infection.
If you encounter a cough from an infected person, when the bacteria in the sneeze are outside the body, they will be divided into more than 40,000 small drops, each of which contains a large amount of viruses and bacteria. The velocity of the liquid can be as high as 35 meters per second, and the propagation distance can be 3 to 8 meters.
According to this scope, if there is an infected person on a bus, his sneezing will give everyone in the car a chance to get infected, and the next person who gets on the bus may also be infected.
Therefore, wearing a mask is to better protect yourself, to avoid contact with the crowd, to prevent contact with infected people. After all, the incubation period of this virus will be as long as 14 days after being tested. You never know, no matter who you passed by, where you have been or what you have been in contact with.
