These two wrong ways of wearing

are very harmful

Some people wear a mask for two or three days, especially the older generation always think that it is too wasteful to change the mask, so simply a mask repeatedly wear. In this case, the mask will be contaminated with some dust, bacteria, water vapor and saliva, if you can not do diligent change, these residual bacteria and viruses, not only can not play a protective, but also may play a counterproductive role.

Wearing masks for a long time also has certain harmful effects. With the extension of mask wearing time, the protection ability of masks decreases continuously, and the hot and humid mask environment is very suitable for bacteria proliferation, which increases the infringement of harmful substances on the skin. In addition, wearing a mask for a long time may cause the mucous membrane of the nose to lose its ability to increase temperature, and the cold air will stimulate the nasal mucosa, which will cause a cold if you are not careful.

So

What do I need to pay attention to when wearing a mask?

Insist on wearing a mask

Wearing a mask is an important protective measure against respiratory infections and can reduce the risk of novel coronavirus infections. The mask not only prevents the patient from ejecting droplets and reduces the volume and speed of droplets, but also blocks the nucleus of droplets containing the virus and prevents the wearer from inhaling them.

Continue to wear a mask even after getting vaccinated against the new coronavirus

For individuals, the protective effect of vaccination against the new coronavirus is not 100%, and it takes some time to produce protective antibodies; for groups, the new coronavirus still spreads easily without forming an immune barrier. Therefore, some preventive and control measures should still be adhered to at this stage, including wearing masks, keeping social distance, washing hands regularly, and more ventilation and other protective measures.

In public places and poorly ventilated

Confined spaces need to wear masks

Wear a mask when riding in closed transportation, such as airplanes, high-speed trains, subways, buses, and when riding in compartment elevators.

When going to the hospital or accompanying friends and relatives to see a doctor, you must wear a mask.

In addition, you should also wear a mask at public service windows, such as supermarket checkout counters, bank counters and other places.

How to wear a mask correctly

Patients with underlying respiratory diseases need to use protective masks under the guidance of a doctor. Very young infants and children should not wear masks to prevent suffocation. Cotton gauze masks, sponge masks and activated charcoal masks are not protective against viral infections.

01

Clean hands

Pay attention to daily hand hygiene and wash your hands when wearing and taking off the mask.

02

Identify the positive and negative sides

Before wearing a mask, turn the nose-clip side of the mask upward and the dark side outward. If there is no color difference in the mask, you can judge the mask by its folds, and the folds are outward.

03

Tight fit

When wearing the mask, place both fingers in the middle of the metal nose clip, press inward while moving the fingertips along both sides of the nose clip until the nose clip is completely pressed against the nose and the mask fits completely with the face, leaving no gap. Inhale quickly at the same time to check if air is leaking from the edge of the mask including the bridge of the nose, and then adjust the nose clip.

04

Splash-proof

You do not need to take off the mask when sneezing or coughing, you can change it at the right time; if you are not used to it, you can take off the mask, but you need to cover your mouth and nose with a tissue or elbow.

05

Change regularly

When the mask is deformed, wet or dirty, resulting in reduced protection performance, it is recommended to replace the mask with a new one immediately to avoid affecting the protection effect. Wear each mask for no more than 8 hours in total. It is not recommended to reuse masks that have been used in environments such as inter-regional public transportation or hospitals.

06

Hanging put

When masks that are used for a short time each time and need to be reused are not in use, they should be hung in a clean, dry and ventilated place.

07

Unsuitable for removal

If you experience any discomfort such as suffocation or shortness of breath while wearing the mask, go to an open and ventilated place to remove the mask immediately.

08

Carry a spare

Carry a spare mask when you go out and store it in the original bag or a clean storage bag to avoid extrusion and deformation. In addition to single-use medical masks and medical surgical masks, it is recommended to stock up on protective masks.

09

Protecting children

When helping children to organize their masks, do hand hygiene. Do not touch the child's mask, face or head with unclean hands.

How to dispose of used masks

Citizens in medical institutions can put masks directly into medical waste garbage bags. As medical waste, masks will be centrally disposed of by professional disposal organizations.

Citizens in ordinary homes can throw used masks directly into the trash because of the lower risk.

Citizens with symptoms such as fever, cough or contact with such people are recommended to throw the masks into the garbage first and then make a 5% 84 disinfectant solution in the ratio of 1:99 and sprinkle it onto the masks for disposal.
