Self-isolation should be carried out after contact with an infected person during the period of new pneumonia, or after suspected contact with an infected person, or after returning from an infected area. The precautions can be as follows: 1. During self-isolation, it is best to live alone, or in a separate room if conditions permit; 2. Avoid contact with family members as much as possible, for example, don’t go into the living room to chat with family members. In the necessary contact is best to maintain a distance of more than 2m, at the same time to wear a good mask; 3, in the isolation period often open the window ventilation; 4, to ensure early to bed and early to get up and get enough sleep, nutrition should also be adequate, to maintain their own best resistance; 5, in the isolation period, do not re-visit friends and relatives, and do not accept other people’s visitation. Because there have been cases reported from the return to Beijing before the start of work at home quarantine 14 days, and in the quarantine period and from the hometown of people contact, resulting in being infected. Although it is true that they were isolated for 14 days, they were actually infected during those 14 days, and soon after they returned to work, symptoms appeared, resulting in more than a dozen people in the organization being infected. Therefore, in addition to ensuring that you do not leave the house during self-quarantine, you should not receive any other visitors. Source: Dr. Yurai
