On the 17th, the joint prevention and control mechanism of the State Council of China held a press conference on the prevention and control of normal epidemic situations and the promotion of occupational health. Feng Luzhao, a researcher at the Chinese Center for Disease Control and Prevention, said that under conditions of good ventilation and a safer social distance, masks may not be worn, such as parks and streets with fewer people, especially during strenuous exercise; and in more closed public places And hospitals, etc., should wear masks.

At the press conference, a reporter asked questions about the service industry, especially the housekeeping and catering industries. The daily flow of employees is relatively large. How can practitioners in these industries protect themselves, is it necessary to wear masks throughout the day in low-risk areas?

Feng Luzhao said that the domestic new crown epidemic should still face the risk of sporadic cases, overseas imports and clustered epidemics for a long period of time in the future. Catering, supermarkets, including transportation and other service industries, as well as public window staff, because of work reasons, the number of people contacted is relatively large, the distance is relatively close, and the infection status of these people is unknown, so adhere to good hygiene habits and be good For protection, wear masks and do hand hygiene during work.

As far as possible, a safe social distance can be maintained, and the workplace must be well ventilated and clean. Of course, daily health monitoring should be done. If there are suspicious symptoms such as fever, dry cough, and fatigue, you should leave your post immediately, seek medical treatment as soon as possible, and do a good job of investigation.

Regarding the problem of wearing masks, Feng Luzhao stated that one principle can be followed, that is, under good ventilation and able to maintain a relatively good and safe social distance, you can not wear a mask, including the following situations:

One is that outdoors, such as parks and streets with fewer people, including playgrounds, do not need to wear masks, especially during intense exercise.

The second is the low-risk areas where no new cases have been reported recently. In offices, meeting rooms, construction sites, and schools, we can maintain ventilation and relatively safe social distance, and we do not need to wear masks.

However, there are three situations where it is recommended to wear masks: First, in some closed public places, such as public transportation, elevators, and public places with many people, it is recommended to wear masks, because this may contact some unknown infection status personnel.

The second is to wear masks when people are sick, especially when fever and cough respiratory infections occur. This is mainly to avoid passing on these sources to other people. This is not only during the epidemic, but also at all times in the future. People need to wear masks.

The third is to wear a mask in the hospital premises in a specific environment, such as going to a hospital, whether to go to the hospital for treatment, or to accompany relatives and friends to a medical institution. Therefore, it is recommended to wear masks in these three situations to reduce the risk of infection.
