It is currently recommended that returnees from the field be quarantined at home for 14 days. If there are home quarantine personnel, when opening windows for ventilation, you need to pay attention to the quarantine house as far as possible in the downwind direction. Other precautions are as follows: 1. Home quarantine personnel should live in a separate room; 2. If the situation allows, have a separate bathroom; 3. Avoid going out as much as possible; 4. Use meal sharing; 5. Pay attention to environmental disinfection; 6. Monitor closely. If there are people in the home isolated, try not to live together with others. If you must live together, be sure to closely monitor the body temperature. If there is discomfort, you should report and seek medical attention in time. Content source: Dr. You Lai
