Is it contagious for both parties to chat with masks? Is the respirator safe?

Novel coronavirus swept across the land of China, and all regions were engaged in a war without smoke. However, with the efforts of medical staff, government departments and the public, the epidemic situation has been controlled to a certain extent. So is there a high probability of infection under effective masks on both sides? Let's have a look!

Can the two sides be infected by wearing masks to chat? No matter what kind of mask you wear, even the N95 protective mask currently used by front-line medical staff can't stop 100% virus transmission. Wearing a mask can only be said to achieve self-protection and reduce the risk of respiratory infection. Pay attention. Because even the N95 mask with this protection level is only over 95%. Moreover, any type of mask has a time-limited protective effect and must be replaced regularly. If it is contaminated, it must be replaced as soon as possible. At the same time, wearing a mask also involves whether it is ready to wear and whether the tightness is intact. This is more or less a risk of infection.

Is the respirator safe? Both parties or one of them wears a breathing valve mask. This is a kind of mask that we absolutely don't recommend wearing, because wearing a breathing valve mask, the gas exhaled by the wearer is not completely filtered and can be directly discharged into the surrounding environment. Therefore, the mask of breathing valve only protects the person wearing the mask, not the people around the person wearing the mask, which is an irregular medical mask. It is even more dangerous if it is worn by infected people. If you bring it yourself, it is risky, because the breathing valve itself belongs to mechanical structure. If it is broken, it has no filtering effect. You don't know. It's a lie!

How to do personal protection during the epidemic? During the epidemic, you must be careful for the health of yourself and your family. If the other person has a history of epidemiology or has been in contact with an epidemic area, don't say it. If you can't meet, don't meet, and advise him to actively report his trip to the community or the local CDC. This is not a matter of good or bad feelings, but a matter of life and health, which is also good for both sides.

I have eighteen truths about personal protection, that is, "Go out less, don't get together, wear masks, ventilate frequently, wash your hands more and stay up late less", don't believe in rumors, don't spread rumors, keep a good attitude, and actively cooperate with epidemic prevention personnel to take various epidemic prevention measures.

Wearing a mask is only part of preventing infection, and it also involves the distance between the two sides of the chat. If two people are close together, there is still the possibility of being spread by droplets. Because we sneeze alone, we will probably produce more than 40,000 drops, some of which will fall to the ground due to gravity within the range of 1-3 meters, but there are still some small drops, although they carry a small amount of poison, and because they are all small, they will spread to far places, just like smokers can still smell the smoke after walking for a long time.
