How long can you wear a disposable mask for the new pneumonia

The novel coronavirus is a highly contagious emerging infectious disease that spreads mainly through respiratory droplets and close contact. At present, the understanding of the disease is not sufficient, and there is a lack of effective drugs or methods in clinical treatment.

The main measures to prevent infection in daily life are personal protective measures such as wearing surgical masks and washing hands frequently, and it is necessary to pay attention to the time when wearing masks and change them in time.

Under normal circumstances, it is recommended to replace the mask with a new mask every 4 hours or so, or when the mask is wet and deformed, it should be disinfected and discarded in time to avoid secondary pollution.

Due to the different materials and filtration efficiency of different types of masks, the specific use time and precautions will also vary:

1. Ordinary medical masks: This kind of mask is made of non-woven fabric, which has a certain blocking effect on particulate matter, but cannot block bacteria and viruses, and has poor air permeability;

2. N95 mask: It is a professional medical mask, which has the effect of efficiently filtering the tiny particles in the air, which can effectively prevent the lungs from inhaling harmful substances, and is usually suitable for medical personnel and people with special occupational needs;

3. KN90 mask: This is a dust-proof mask, which is mainly used for dust that is harmful to the human respiratory system in industrial production, such as metal mineral powder, asbestos fiber, etc., and can also be used in operating rooms, laboratories and other places in medical institutions to avoid microorganisms floating in the air from entering the human body and causing diseases.

In addition, if you have symptoms such as fever and cough, you need to go to the hospital as soon as possible, and complete blood routine examination, chest CT and other related auxiliary examinations to confirm the diagnosis. Patients diagnosed with novel coronavirus infection need to take antiviral drugs such as Lianhua Qingwen Capsule and Golden Lotus Soft Capsule for treatment according to the doctor's instructions. At the same time, you also need to pay attention to rest, maintain adequate sleep, eat more fresh vegetables and fruits in your diet, and supplement the nutrients needed by the body.
