Before entering the office building, you should consciously accept the temperature test, and only enter the building to work after the temperature is normal, and go to the bathroom to wash your hands in time. When you enter the office area to work, open the windows appropriately for ventilation if you can, avoid the air in the confined space from not circulating for a long time, and pay attention to keep a certain safety distance from your colleagues and try to wear a mask to ensure your health. If your body temperature exceeds 37.2°C, do not enter the building to work and go home to isolate yourself, observe and rest, and if necessary, go to the nearest hospital for medical treatment.
