A positive new crown is generally defined as a positive nucleic acid test result for a novel coronavirus, which takes days to months to resolve in some mild cases, and does not resolve in more severe cases. A positive test result for novel coronavirus nucleic acid may indicate that the body is infected with the novel coronavirus, but it is still necessary to combine the results with other tests to diagnose the disease. For those who test positive for the novel coronavirus and are clearly mildly ill and in good health, there is some chance of spontaneous recovery, which may take days to months, but there is no definitive data to confirm this. In the more severe cases, those who are immunocompromised are usually unable to recover on their own and need to be actively treated by their doctors. Clinical findings show that the prognosis is relatively good for those who are actively treated, while those with severe disease who are not actively treated are likely to have their disease aggravated, or even their lives jeopardized. Patients should pay attention to adjusting their mindset, establishing a correct understanding of the disease and confidence in overcoming the disease.
