If a new coronavirus nucleic acid test comes back positive, the person will always be notified. If a new coronavirus nucleic acid test is positive, the patient will be notified and immediately quarantined and treated. Isolation and testing will also be carried out on relevant persons who have had close contact with the patient. The new coronavirus spreads quickly and widely. Therefore, in order to prevent mass transmission of the virus, it is important to manage a positive nucleic acid test as soon as it is confirmed. Immediately after the positive nucleic acid test result of a patient is available, the local epidemic prevention and control department and CDC’s flow control personnel will identify close contacts and sub-closely contacts according to the patient’s movement track and carry out relevant management measures. In case of abnormal nucleic acid results, the patient should actively cooperate with the treatment so as not to delay the disease.
