Is it necessary to wear masks all day in low-risk areas? Regarding whether to wear a mask, we can follow a principle, that is, when the ventilation conditions are good and a relatively good and safe social distance can be maintained, the mask can not be worn, including the following situations:

One is that outdoors, such as parks, streets with few people, including playgrounds, do not need to wear masks. Especially during strenuous exercise, you should not wear a mask.

The second is low-risk areas where no new cases have been reported recently. In fact, we don’t need to wear masks even if we can maintain ventilation and relatively safe social distance in offices, conference rooms, construction sites, and schools.

However, there are three situations where we recommend wearing a mask:

One is that in some relatively closed public places, such as public transportation, elevators, and crowded public places, it is recommended to wear masks, because as mentioned earlier, people with unknown infection status may be contacted.

The second is to wear a mask when someone is sick, especially when symptoms of respiratory tract infections such as fever and cough appear. The main reason is to avoid spreading these diseases to other people. This principle must be followed not only during the epidemic, but at all times in the future. , People who are sick should wear a mask.

Third, in a specific environment, such as going to a hospital, whether you are going to a hospital or accompanying your relatives and friends to a medical institution, you must wear a mask in a place like a hospital. Therefore, in these three situations, it is recommended to standardize the wearing of masks to reduce infection risks of.
