Since the clinical manifestations of New Coronary Pneumonia are similar to many common diseases and are contagious, patients are advised to go to the hospital immediately for a systematic examination to determine if they are infected with New Coronary Pneumonia and to receive active treatment. Patients who are not infected with New Coronary Pneumonia should also be treated for the cause of the fever for early recovery and also for self-protection against New Coronary Pneumonia. The diagnosis of New Coronary Pneumonia is mainly confirmed by the results of nucleic acid testing, lung CT, and blood tests. After the patient is diagnosed with neo-coronary pneumonia, on the one hand, anti-inflammatory therapy is required, commonly using glucocorticoids such as dexamethasone, on the other hand, antioxidant therapy with drugs such as vitamin E and N-acetylcysteine, and also antiviral therapy through drugs such as ribavirin, abirater, raltegravir, and favipiravir. New coronary pneumonia can also cause hypoxia and respiratory distress in patients. Depending on the degree of hypoxia, general oxygenation, high-flow mask oxygenation, and noninvasive mechanical ventilation are chosen. If the patient is not infected with neo-coronary pneumonia, the fever may be caused by the common cold. In mild cases, the patient may pay more attention to rest, drink more water, use physical cooling and observe changes in the condition. If there is high fever or the temperature continues to fail to lower, it can also be relieved by taking antipyretic and analgesic drugs such as ibuprofen, busulfan, acetaminophen, etc. Patients with influenza also need antiviral treatment, and the general course of the cold can be recovered within 5-7 days. Fevers caused by pneumonia, tuberculosis and other respiratory diseases often require targeted anti-infection and anti-tuberculosis treatment, and the specific treatment plan needs to be decided by the doctor after the cause of the disease is clarified.
