What is influenza?
Influenza (influenza for short) is an acute respiratory infection caused by influenza virus. It is also a highly infectious and fast spreading disease. It is mainly transmitted by droplets in the air, human to human contact or contact with contaminated objects.
Why do we advocate wearing masks?
In winter and spring, when there is a high incidence of respiratory infectious diseases such as influenza, wearing a mask is not only to protect yourself from being infected by others, but also an effective measure to protect the people around you when you have respiratory symptoms. It is like setting a "filter barrier" for your respiratory system.
How to choose a mask?
At present, there are many kinds of masks on the market. According to the different materials and filtration efficiency, there are three kinds of masks: one is the cotton gauze mask with cold protection and heat preservation and the lowest filtration efficiency; the other is the disposable medical mask with slightly higher filtration efficiency and poor tightness; the other is the functional protective mask with the highest filtration efficiency and the best protection effect, such as zhongkestar class a mask, which can It can effectively meet the protection needs of influenza virus.
How to wear a mask?
If the mask is not worn correctly, the effect will be greatly reduced. Whether it is disposable masks or protective masks, the most important thing to wear is to ensure the airtightness, which requires choosing the suitable model.
According to the data of human head model, the size of the mask is designed scientifically, and the large-scale crowd wearing test evaluation is carried out. The reference method of quickly selecting suitable mask according to the index of "shape and face length" of face is proposed for you to choose the suitable mask.
Wear protective mask, need to ensure the fit with the face. After wearing the mask, it is necessary to check the tightness of the mask. Through rapid breathing, check whether there is air leakage on the nasal side and cheek, so as to check the tightness.
How to store masks?
When there is a high incidence of respiratory infectious diseases such as influenza, we should carry masks with us so that they can be used at any time. According to the degree of air pollution, the recommended wearing time of the respirator is provided. The mask can not be washed with water, but can be used repeatedly. When temporarily stored, because the exhaled moisture is absorbed after wearing, it is better to put it in a dry place to let the moisture dissipate, and then keep it in a clean sealed bag.
