A positive New Crown is generally defined as a positive nucleic acid test, and not only will a report be issued, but immediate action will be taken to deal with the positive patient and the closely infected person. When a positive nucleic acid test result occurs after a nucleic acid test, it is possible to be infected with the New Crown virus. Generally, after other tests of the same type and judgment by professional doctors, false positives are ruled out and a clear diagnosis is made, not only will a corresponding report be issued and the infected person be informed immediately, but the patient will also be isolated for treatment. Those who have been in contact with such patients are called close contacts, and after tracking and investigating their movements by CDC professionals, they are also required to undergo nucleic acid testing and isolation immediately to prevent the virus from spreading on a large scale. If the nucleic acid test is positive, the patient should actively cooperate with the treatment and build up confidence in overcoming the disease.
