Wear a mask to prevent a stream, be careful when buying and wearing

At present, it is the high incidence of various respiratory diseases with a high prevalence of influenza A. Many citizens choose to wear masks to prevent diseases and prevent cold. Experts from the Department of Disinfection of the Municipal Center for Disease Control and Prevention said that they visit patients, visit hospitals or crowded people, and the air is not available. It is right to wear masks to prevent diseases in public places that are circulated. However, if the masks are not qualified or worn unqualified, the protective effect of the masks will be greatly reduced or lost, and even some other hazards will be caused to the human body. The disinfection expert reminded that wearing a mask to prevent an epidemic should be careful when buying and wearing it.

According to experts, currently the market's disease prevention masks mainly include N95, surgical masks, gauze masks, and cotton cloth masks, etc. The main route of transmission of A stream is close-range droplet transmission. The above-mentioned masks and proper wear will play a protective role. . However, in the past two years, a variety of colorful fashion "cartoon" masks have become a popular trend. They can be bought in a few jewelry stores and can be purchased for a few dollars. These masks are simply packed in a transparent plastic bag and they are basically found on the packaging. Not any information about the manufacturer. Useful for gauze, protects the respiratory system and prevents germs. Some of them are made of polyester fibers, and a cartoon pattern is printed on the surface of the mask. This mask is fashionable but it does not necessarily protect the respiratory system. The low-cost printing and dyeing masks contain chemical fibers and are printed on the front with colorful cartoon patterns, which have poor air permeability. Health people who wear this type of mask do not benefit the respiratory system. Chemical fiber fabrics may irritate the bronchus. Some of the masks that are dyed are unqualified and cause skin allergies and unpleasant noses. Some patients with allergies and asthma wearing this kind of mask may worsen the condition.

Experts warn that the state has strict regulations on the thickness, number of layers, and breathability of masks, as well as safety requirements. For general textiles, there are five indicators such as color fastness, formaldehyde, pH, and banned carcinogenic dyes. Fashion masks do not belong to medical masks and are not strictly disinfected. Many masks are not made of pure cotton yarn and contain many polyester fibers. Some drawings have only 2 to 4 layers of lightweight gauze, making it difficult to effectively filter out viruses and dust in the air. Some masks are too large or too small to fit tightly and comfortably on the face. Dirty air is drawn into the body without filtering. So try not to buy fashionable "cartoon" masks. When you buy other masks, you must rely on your hand. More than 12 layers of regular "multilayer" masks are available. The masks are soft, flexible, thin and uniform, and have no obvious agglomerates. And those inferior masks have some sandwiches made of hard plastic, some are rotten gauze, some are thin and soft facial tissues. If you carefully examine them, you can feel obvious on your hand. The second is to look at packaging. Masks produced by regular manufacturers are packaged according to strict regulations. When consumers purchase, it is best to choose mask products with independent small packages to minimize secondary pollution. In addition, when purchasing, it should also pay attention to the approval of production numbers, trademarks, plant names, site and telephone and other production information. The third is the selling point. Consumers are advised to purchase masks from regular shopping malls, supermarkets and pharmacies. The prices of 12 to 16-layer masks are generally around three to four yuan. In some small commodity markets, 1 to 2 yuan of "cheap goods", consumers should be careful to buy. In addition, the best choice for the nose clip, the protective effect will be better.

If you choose a suitable mask, if you don't wear it well, your protection will be greatly reduced. When you wear a mask, you must completely cover your mouth and nose. You can't just cover your mouth because it's called a mask. When wearing a mask, distinguish between inside and outside, do not interchange, if you wear the outside, and later changed to wear inside, you will inhale a lot of bacteria, viruses. Prepare more masks. Always wash them frequently. It is best to sterilize them for 10 minutes. Wash, dry, and pack in a timely manner. In principle, each mask should not be worn for more than two hours or up to one day. Also don't sprinkle aromas on masks, because aromas can irritate the respiratory system, induce respiratory diseases, and don't touch them often with your hands.
