Expert in normalization of epidemic prevention and control: wearing masks "three musts" Air conditioning can be used normally in public places
China-Singapore Online, May 8 (Reporter Chen Jing) The prevention and control of the new coronary pneumonia epidemic has become normal. How should I wear a mask? Do children have to wear masks after physical education? Can buildings and buses turn on air conditioning? These are issues of public concern.
Wu Huanyu, director of the Shanghai Centers for Disease Control and Prevention, said on the 8th that the mask wearing requirements are summarized as "three musts" and "two suggestions." The three "musts" are: persons with symptoms of fever, nasal congestion, runny nose, cough and other accompanying persons must wear masks when visiting medical institutions or in public places (occasions); medical personnel, public service industry practitioners Persons and personnel involved in epidemic prevention and control must wear masks while on duty; take rail transit or long-distance buses to enter medical institutions, welfare institutions, schools and other places where the country has clear requirements, they must wear masks.
It is reported that for the elderly and infirm, including those with chronic basic diseases, when going out, it is recommended to wear a mask from the perspective of self-protection; it is recommended that the public carry the mask with you and bring it with a sealed bag. Wu Huanyu said that if you encounter a confined space, a crowded area or need close contact with others, it is recommended to wear a mask as appropriate.
As for whether students need to wear masks in physical education classes and public sports, Wu Huanyu said that if the activities are outdoors or outdoors, and there is no close physical contact project, you can not wear a mask; if the project is indoors, ensure that the air is good In the case of circulation and maintaining a safe distance, it is not necessary to wear a mask. He pointed out that considering that students have not fully recovered their physical fitness shortly after class resumption, it is recommended that physical education classes should be developed step by step. At the beginning, avoid close contact projects, projects with high physical fitness requirements or strong resistance.
Starting from the 9th, Shanghai lowered the emergency response level to three, which means that Shanghai has gradually entered the stage of normalized prevention and control of new coronary pneumonia. Wu Huanyu pointed out that air-conditioning can be used normally in Shanghai's commercial buildings, large shopping malls, rail transit and other public places. He said that the amount of fresh air should be increased, and ventilation should be increased. In the normal use of the central air conditioner, the operation management, cleaning and disinfection and sanitation management of the central air conditioner should be strictly followed in accordance with relevant national standards, and the related equipment parts should be cleaned, disinfected and replaced. When a newly diagnosed or suspected case of new coronary pneumonia is found, the central air conditioning ventilation system should be terminally disinfected under the guidance of the disease control department, and it can be re-activated after passing the inspection (test).
In addition, household split air conditioners and car air conditioners such as taxis and buses can be used normally after cleaning and disinfection of filters and movements. However, Wu Huanyu pointed out that in use, attention should be paid to ventilation and regular cleaning and disinfection. (Finish)
