Interpretation of "Guidelines for Preventing novel coronavirus from Infecting the Public to Wear Masks (April 2023 Edition)" by Provincial Disease Control Experts
These three kinds of situations or scenes should still wear masks.
Haikou, April 15th (Reporter   Marco) On April 12th, the Epidemic Prevention and Control Group of the Joint Prevention and Control Mechanism of the State Council released the Guidelines for Preventing People from Wearing Masks in novel coronavirus (April 2023). On April 15, the provincial disease control experts interpreted this.
Why should we revise the guidelines for wearing masks? It is reported that during the period when novel coronavirus was infected with "Class B A tube", the state successively issued five versions of the guidelines for wearing masks, which played an important role in protecting public health and effectively preventing and controlling the spread of the epidemic. At present, the epidemic situation in COVID-19 in China is generally sporadic, but the global epidemic situation is still prevalent and the virus strains are constantly mutating, so there is still the risk of epidemic rebound in China. According to the epidemic situation and the need of prevention and control in China, on the basis of the first five editions of the guidelines on wearing masks, the Guidelines on Preventing People from Infecting novel coronavirus from Wearing Masks (April 2023 edition) was formulated to guide the public to wear masks scientifically and standardly.
What situations or scenarios?Should I wear a mask?
1 There is a risk of epidemic spread, such as when the public is infected in novel coronavirus or when there are symptoms of suspected novel coronavirus infection;
2 Being in a situation or scene with high risk of infection, such as when there is a cluster epidemic in the community where you live, work or study, and when you go to a medical institution for treatment, accompanying, accompanying or visiting;
3 Strictly guard against situations or scenes in which the epidemic situation is imported into key institutions. For example, foreigners should wear masks when entering places where vulnerable people are concentrated, such as pension institutions, social welfare institutions, child care institutions, schools, off-campus training institutions and other public service personnel should wear masks throughout their work to prevent the epidemic situation from being imported into relevant key institutions.
What situations or scenarios?Suggest wearing a mask?
1 Entering areas or places with large traffic or closed environment and crowded people, such as taking public transport, entering supermarkets, theaters, passenger stations, etc., once novel coronavirus-infected people exist in relevant areas or places, it is easy to spread the epidemic due to crowded people, poor ventilation and other reasons;
2 The elderly, patients with chronic basic diseases, pregnant women and other special groups are more harmful after infection, so it is recommended to wear masks when going to indoor public places to strengthen self-protection;
3 For large-scale meetings or activities with a wide source of personnel and strong mobility, if the participants do not carry out nucleic acid detection or antigen detection and health monitoring, once an epidemic situation is imported, it is recommended to wear a mask.
What situations or scenarios?Don’t wear a mask?
1 Situations or scenes with low risk of infection, such as outdoor places such as open squares and parks, or indoor places and conference rooms with relatively fixed personnel;
2 A situation or scene where the risk of infection is effectively prevented, such as holding a large-scale meeting or activity, by conducting nucleic acid detection or antigen detection and health monitoring on the participants, potential infected persons can be found in time;
3 A situation or scene where the risk of infection is low and wearing a mask may have a certain impact on work, life and study, for example, infants under 3 years old, teachers and students at school, people who are exercising, and people who may have difficulty breathing when wearing a mask.
How to choose to wear itSuitable type of mask?
Experts said that in view of the high risk of spreading the epidemic in novel coronavirus infected people and suspected infected people, it is suggested that they wear N95 or KN95 particulate protection masks or above (without breathing valves), while others suggest wearing disposable medical masks or surgical masks, and pay attention to changing masks in time.
