1. Wash your hands frequently. Wash your hands with soap or hand sanitizer and tap water, and wipe your hands with disposable paper towels or clean towels. Wash your hands immediately after contact with respiratory secretions (such as sneezing).

2. Maintain good respiratory hygiene habits. When coughing or sneezing, cover your mouth and nose with paper towels and towels. Wash your hands after coughing or sneezing, and avoid touching your eyes, nose or mouth.

3. Enhance physical fitness and immunity. Balanced diet, moderate exercise, regular work and rest, to avoid excessive fatigue.

4. Keep the environment clean and ventilated. Open the window for ventilation several times a day, at least three times, each time for 20-30 minutes. When the outdoor air quality is poor, the number and time of air exchange should be reduced appropriately.

5. Minimize activities in crowded places and avoid contact with patients with respiratory infections.

6. If you have symptoms of respiratory infection such as cough, runny nose and fever, you should rest in isolation at home. If your fever persists or your symptoms get worse, you should seek medical advice as soon as possible.
