With novel coronavirus pneumonia, if the patient’s body has good immune function, it is possible to recover spontaneously; if the immune function is poor and combined with underlying diseases, it is unlikely to recover spontaneously. The prognosis of patients with novel coronavirus pneumonia is related to the state of immune function. Some patients have no underlying disease, normal immune function, and have no obvious symptoms or only mild symptoms after infection with novel coronavirus. These patients are asymptomatic infected patients or mild patients, and usually can recover from the disease after resting and strengthening nutrition. However, for patients with poor physical condition who are prone to severe illness, such as the elderly, tumor patients, patients with chronic diseases, and people with low immune function, once they get infected with novel coronavirus pneumonia, their condition is usually more serious and prone to complications, so they need to be actively treated and cannot wait for self-cure. In order to prevent the new coronavirus pneumonia, it is recommended to wear a good mask when you go out, pay attention to hand hygiene and disinfection when you return home, and get vaccinated against the new coronavirus pneumonia as soon as possible when conditions permit. Tip: On December 26, 2022, the National Health Commission issued an announcement to change the name of “new coronavirus pneumonia” to “new coronavirus infection”.
