How to choose a mask?
Wearing a mask is an effective way to stop the spread of respiratory secretions. Currently, there are mainly medical protective masks (such as N95), medical-surgical masks and ordinary disposable surgical masks available on the market. In addition, there are a variety of stars on the market often worn cotton masks, sponge masks.
It is good for citizens to choose medical surgical masks for daily protection. The N95 mask is more effective in preventing disease, but it is not suitable for long-term wear due to its poor air permeability and high respiratory resistance.
How to wear a mask correctly?
When wearing the mask, the folded face will be fully expanded, the mouth, nose, chin completely covered, and then press the nose clip, so that the mask and the face completely fit.
Wash your hands before wearing the mask or avoid touching the inside of the mask while wearing it to reduce the risk of contamination. Should distinguish the inside and outside of the mask, up and down, light colour for the inside, the inside should be attached to the mouth and nose, dark side outwards; There is a metal strip (nose clip) on one end above the mask.
Mask should be changed regularly, and can not wear inside and outside inside, and you can not wear it on both sides in turn.
Is it possible not to wear a mask in places where people are not dense?
If going to a crowded place, wearing a mask is necessary because the person is much, not ventilated, and it is likely that ill original is in your surroundings. But where the population is not dense, if the environment is open, the pathogen is diluted, not enough to infect people, you can not wear a mask. But if you have a cough, fever and other symptoms, in order to prevent the infection of others, you need to wear a mask.
Masks are in short supply. Can you repeat them? Can you repeat after boiling?
Surgical masks should not be reused. In principle, the same is true for N95 respirators.
But the reality is that for ordinary people, masks are now in short supply. If there is no fever or symptoms of catarrh (runny nose, sneezing, nasal congestion, etc.), it can be used repeatedly and the number of repetitions should not exceed 5.
But we still want to emphasize the dangers of reuse. The protective effect of the mask is weakened after boiling. It is not recommended to reuse the mask in this way.
In addition to wearing masks, we emphasize washing hands frequently. After the new coronavirus through hand contact, and then to touch the nose, mouth and another mucous membrane to enter the body, through soap and flowing water washing hands for more than 20 seconds can effectively kill pathogens to play a protective role.
