Why wear a mask?

      The main route of transmission of the new coronavirus is droplet transmission, which can be effectively blocked by wearing a mask. Masks are an important line of defense against respiratory infections and can reduce the risk of new coronavirus infections. The mask can not only prevent the patient from spraying droplets, reduce the droplet volume and spraying speed, but also block the virus-containing droplet core and prevent the wearer from inhaling.

How to wear a mask?

      (1) Masks are not required in the open and ventilated areas of non-infected areas, and masks are required when entering densely populated or closed public places.
     (2) It is recommended to wear single-use medical masks in open and ventilated places in areas with high incidence of epidemics; medical surgical masks or particulate matter protective masks should be worn in crowded or closed public places.
     (3) When you come to the hospital with suspected symptoms, you need to wear a particulate protective mask or a medical protective mask without an exhalation valve.
     (4) Patients with basic respiratory diseases should use protective masks under the guidance of a doctor. Young infants and young children cannot wear masks, which can cause suffocation.

The masks used by healthy people can be disposed of according to the requirements of domestic waste classification.
