Some people always think that as long as you wear a mask, no matter how you wear it, you will have no problem defending against the virus. But this kind of thinking is wrong. There are correct and standardized ways to wear masks. If you don't wear them as required, the virus can take advantage of it at any time.
Not all masks can play an anti-virus effect. At present, there are many types of masks on the market, such as paper masks, activated carbon masks, cotton masks, and sponge masks. Because their materials are not dense enough, the preventive effect is relatively poor. At present, the masks that can play an anti-virus effect on the market mainly include disposable medical surgical masks, KN90, KN95, and N95. The anti-virus capabilities are gradually increasing from left to right.
Whether you are wearing a mask or taking off a mask, you should clean your hands carefully. If you do not wash your hands before wearing a mask, it may contaminate the mask and increase the risk of infection. Therefore, you should strictly clean your hands before wearing a mask, and dry your hands before wearing the mask.
