Remind citizens and friends that the winter weather is cold, people spend more time in confined places, and the risk of respiratory infectious diseases increases. Avoid going to crowded places and develop a good habit of carrying masks with you. You must wear a mask when taking public transportation, elevators, going to the hospital and other relatively closed places with many people, and pay attention to keeping a safe social distance of more than 1 meter with others. Opening windows for ventilation can introduce fresh outdoor air, dilute the indoor air, and effectively reduce the number of pathogenic microorganisms in the air. It is one of the important means to prevent respiratory infections. Even if the weather is cold, keep opening windows for ventilation, 2-3 times a day, every time 10-20 minutes to allow indoor air to flow. You can open doors and windows or multiple windows at the same time to form convection, or you can ventilate all rooms one by one. When windows are ventilated, you should pay attention to cold and warm, especially those with weaker resistance such as the elderly and children in the house should be warm and protected to avoid catching cold.
