Windows can be opened for ventilation during the epidemic.
Opening windows for ventilation during an outbreak is recommended about 2 to 3 times a day, each lasting about 30 minutes. Ventilation can facilitate air flow, thereby reducing the possible presence of viruses in the room, and also helps to renew the air in the room. Keeping the air circulating will help dilute the concentration of the virus in the air, thus preventing infection.
The possibility of aerosolized infections may also increase when the air in the room is relatively closed, and opening windows daily can help to reduce the possibility of aerosolized infections and the risk of respiratory droplet transmission. Take care to prevent upper respiratory tract infections and do not open windows for ventilation during foggy weather.
In addition to opening windows for ventilation during the epidemic, it is also recommended to pay attention to hand hygiene, timely cleaning of hands, using running water to wash for more than 15 seconds to go out and pay attention to wearing a mask, avoid going to crowded places, pay attention to the people with a separation of more than one meter and so on.
