On March 24, according to Xinhua News Agency, Sheng Jifang, deputy director of the State Key Laboratory of Infectious Diseases Diagnosis and Treatment and director of the Department of Infectious Diseases of the First Hospital of Zhejiang University, said that from the perspective of infectious diseases, the public should develop a good habit of wearing masks. "Flu season, high incidence of infectious diseases, crowded places and indoor confined spaces are still recommended to wear masks. Develop good living habits, enhance physical and mental resistance, and create a good public health environment."

 

For the public, when can I be sure to take off my mask?

 

Precise prevention and control are essential, orderly return to normal life

 

Zhang Wenhong, head of the Shanghai New Coronary Pneumonia Medical Treatment Experts Group and director of the Infection Department of the Huashan Hospital Affiliated to Fudan University, said that most local epidemic prevention and control emergency response levels have been lowered, and the reduction is based on evidence. It is almost zero, and the probability of transmission is very low. In this case, most people in the surrounding area are unlikely to be infected. Except for hospitals, crowded people, and subways, masks can be removed.

 

Zhang Wenhong said: "People like to be told clearly whether they want to wear it. In fact, it is related to your environment. Under normal circumstances, the necessity of wearing is gone. In high-risk environments, it is best to wear it."

 

The reporter noticed that in the guidelines for the use of masks in some places, indoor rooms with good ventilation, which can ensure the separation of personnel, and take anti-kill measures can be conditionally removed.

 

Experts said that masks are not taken away. The test of social governance is behind the removal of masks. Accurate management and control, technical empowerment and mechanism guarantee are indispensable. For example, in parks, stadiums and other places, capacity can be calculated so as to "limit current", do a good job of control, and avoid the situation of people gathering. For example, Shanghai Century Park, while doing a good job of disinfecting and shortening the opening time of the park, lowered the maximum carrying capacity of tourists in the whole park to the standard of 50% of the tourist reception in the same period of the past years. In order to avoid crowds of flowers in the spring, the West Lake Scenic Area of ​​Hangzhou has imposed restrictions on the viewing of fishes and botanical gardens in Huagang. Tourists need to make an appointment through the APP, and the flow of people exceeding 10,000 is restricted.

 

Anti-epidemic measures can not be relaxed, control the density of people in public places

 

Experts said that the current epidemic situation in foreign countries is very serious, and it is necessary to carefully prevent imported risks. The epidemic situation differs from place to place, and in many places, the task of external defense import and internal defense rebound is still very heavy. To adapt to local conditions, take off the mask and do not follow the trend at random. You still have to wash your hands frequently and keep a distance when going out.

 

"All public places that are open to business must effectively fulfill the main responsibility of epidemic prevention and control." The relevant person in charge of the Zhejiang Provincial Prevention and Control Work Leading Group Office said, whether it is to strengthen ventilation, or to reasonably control the density of personnel in the place, and hygiene Every link of the internal management of epidemic prevention must continue to be closely watched, and post-event supervision should be strengthened.

 

Sheng Jifang, deputy director of the State Key Laboratory of Diagnosis and Treatment of Infectious Diseases, said that from the perspective of infectious diseases, the public should develop a good habit of wearing masks. "Flu season, high incidence of infectious diseases, crowded places and indoor confined spaces are still recommended to wear masks. Develop good living habits, enhance physical and mental resistance, and create a good public health environment."
