New Crown generally refers to new coronavirus pneumonia. New coronavirus pneumonia may heal on its own in seven days, but it is impossible to generalize due to the existence of variability in individual constitution. Patients are advised to consult their doctors and take scientific and reasonable treatment measures, such as medication. New coronavirus pneumonia is contagious and can be spread through respiratory droplets and close contact. Patients may experience symptoms such as fatigue, dry cough and fever. However, some people who have received the new coronavirus vaccine may have asymptomatic infections. The condition of these patients is mild, and if the patient’s resistance is high, there may be a possibility of self-healing. Due to individual differences, it is impossible to generalize. It is recommended that those with obvious symptoms should take relevant treatment measures with the doctor, such as taking oral antiviral drugs like ritonavir tablets and lopinavir tablets or oral glucocorticoid drugs like methylprednisolone as prescribed by the doctor. With standardized medication, patients can control the progression of the disease, relieve symptoms and improve prognosis. Once diagnosed with novel coronavirus pneumonia, patients should take relevant treatment measures according to their own conditions. Tip: “New coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article have been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
