Whether or not an infection with Neocollins can heal on its own is related to the patient’s specific condition and his or her own physical fitness. Usually, mild cases with good immunity are likely to recover on their own, while severe cases of neocoronavirus pneumonia are more likely to fail to recover on their own. 1. Mildly ill patients: by paying attention to rest, increasing nutrition, improving their own immunity, while maintaining a positive and optimistic mindset, it is possible to achieve a state of self-healing without treatment. It is recommended to isolate the patient immediately after the discovery of the infection and to observe the symptoms continuously. If the symptoms continue to worsen due to untreated symptoms, the patient may turn into a severe case, and severe cases must be treated aggressively. 2. Seriously ill patients: For seriously ill patients, especially elderly patients with multiple underlying diseases, most of them cannot recover on their own, and should be treated with active supportive therapy. During the new crown epidemic, both mildly and severely ill patients need to be isolated and treated, rather than waiting for self-healing, so as to better control the patient’s condition and the new crown epidemic. Tip: In this article, “new coronavirus pneumonia” and “new coronavirus pneumonia” have been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
