1. Reduce shared space: For those who are isolated at home, their family members should live in different rooms. If conditions are limited, they should keep a distance of at least 1 m from patients and restrict patients' activities to minimize shared space and ensure good ventilation.

2. Pay attention to hand hygiene: All household isolators should pay attention to hand hygiene, and wash their hands with soap and water before and after cooking, before and after meals, or with alcoholic hand sanitizer.

3. Pay attention to respiratory hygiene: Everyone should pay attention to respiratory hygiene at any time, especially patients. When coughing or sneezing, cover your nose and mouth with a medical mask, paper towel or elbow, and then wash your hands.

4. Frequent disinfection of common articles: disinfection should be carried out on the surfaces of articles in frequent contact, such as bedside tables, bedroom furniture such as bedside tables, and general household disinfectants containing diluted bleach (1: 99) can be used.

5. Attention should be paid to the treatment of pollutants: household isolators should avoid sharing toothbrushes, cigarettes, tableware, drinks, towels, etc. Tableware used by patients should be washed with water, soap or detergent, which can be reused, but not directly discarded.

Precautions:

The observation object should live relatively independently, minimize contact with family members and avoid cross infection. If you can't live alone, you should keep a distance of at least 1 m from other family members.

The room should be well ventilated, and the areas that may overlap need ventilation and disinfection. Air conditioning is not suitable for rooms, especially central air conditioning shared with other rooms. If heating is needed, a heater should be used.
