Nucleic acid mainly refers to the genetic material of RNA or DNA virus. If the nucleic acid of the virus in blood or secretion is positive, it indicates that the virus is infected. If the nucleic acid test is positive, isolation treatment is usually needed, because if the test result is positive, it generally means that COVID-19 is infected, so you must go to a hospital designated by the state for treatment, and at the same time pay attention to isolation to avoid infecting others. If severe patients have dyspnea and decreased oxygen saturation, tracheal intubation or artificial lung treatment is needed in time.
At present, COVID-19 is highly contagious and can be transmitted by respiratory droplets, direct contact and indirect contact. In addition, the incubation period of the virus is about 14 days. During the treatment, you should keep a happy mood and not have too much psychological pressure.
