[Epidemic Prevention · Zhou Zhi] Harbin Centers for Disease Control and Prevention Publishing Mask Use Knowledge

On the 26th, the Harbin CDC released the knowledge of masks.

First, why can the mask prevent infection?

Don't look at a small mask, but it can greatly protect. The mask is composed of non -woven fabrics and melting spray cloths. These special materials can not only prevent the outside world from entering the respiratory tract, but also to avoid the drums sprayed in the air when they sneeze and cough. Studies have shown that as long as both parties wear masks and are intervals of more than 1 meter, the chance of infection is almost 0.

Second, how to wear masks is the most correct?

The mask should cover the nose and nose and chin, the nose clip should be compacted, do not wear multiple masks at the same time, and patients with basic respiratory diseases need to use protective masks under the guidance of a doctor. Babies under 3 years old should not wear masks, which can easily cause suffocation. Parents are prone to suffocation. Try to avoid taking children to dense public places.

How long can the mask be used?

(1) After 4 hours of mask, you need to replace it. When the mask is humid or dirty, you should replace it in time;

(2) Do good hand cleaning before and after wearing;
