Extended data:

It is suggested that Beijing citizens and friends should take measures to prevent cold and epidemic:

First, key people should pay attention to keep warm and reduce outdoor activities. In winter, the temperature difference between indoor and outdoor is large, so clothes should be added in time according to the weather change. Wear warm clothes, hats, gloves and masks when going out. The resistance of the elderly, pregnant women and babies is generally weak, and it is necessary to reduce going out in windy weather. If you need to go out, you should choose to go out at noon when the temperature is high.

The second is to avoid going to crowded closed places. When going to crowded places, pay attention to keeping a social safety distance of at least 1 m from others, and do personal protection such as wearing masks. When there are many passengers, you should wait in line to avoid crowding.

The third is to wear masks scientifically. Develop the good habit of carrying a mask with you. Especially when staying in a relatively closed or crowded space, such as taking public transport, taking elevators, going to hospitals, entering public places, and when there are patients or people with unknown health conditions in the environment, you must wear masks.
