Why wear a mask?
The main route of transmission of the new coronavirus is droplet transmission, which can be effectively blocked by wearing a mask. Masks are an important line of defense against respiratory infections and can reduce the risk of new coronavirus infections. The mask can not only prevent the patient from spraying droplets, reduce the droplet volume and spraying speed, but also block the virus-containing droplet core and prevent the wearer from inhaling.
How to wear a mask?
(1) Masks are not required in the open and ventilated areas of non-infected areas, and masks are required when entering densely populated or closed public places.
(2) It is recommended to wear single-use medical masks in open and ventilated places in areas with high incidence of epidemics; medical surgical masks or particulate matter protective masks should be worn in crowded or closed public places.
(3) When you come to the hospital with suspected symptoms, you need to wear a particulate protective mask or a medical protective mask without an exhalation valve.
(4) Patients with basic respiratory diseases should use protective masks under the guidance of a doctor. Young infants and young children cannot wear masks, which can cause suffocation.

What are the safe masks?
There are many types of masks. The most common are: disposable medical masks, anti-fog masks (BFE standard), N95 (KN95) masks, anti-fog masks, cotton masks, etc.
Because the virus particles are very small, dozens of times smaller than the smallest bacteria, not all masks have anti-virus functions.
Professional N95 (KN95) masks have relatively high protection levels and have good protection effects. This is why N95 (KN95) is used for medical staff.
In addition to professional N95 masks, in fact, disposable medical masks and anti-fogging masks (BFE standard) can also isolate viruses well. There are three layers of non-woven fabrics for medical surgery and anti-fogging masks (BFE standard). The non-woven fabric in the middle layer contains static electricity, which can adsorb tiny particles and prevent viruses from entering the human body.
Although some viruses can pass through the layers of the mask to block their entry into the human body, since there are fewer individual viruses entering the human body, the concentration of the virus cannot be reached, and the immune system can destroy them, so it will not cause human illness.
According to research, non-woven masks with static electricity can play a very good protective effect.
Therefore, masks can play a good role in preventing and controlling the Covid-19 epidemic. So why don't foreigners wear masks?
