Some patients with mild novel coronavirus infection may heal spontaneously without exacerbation within a period of 1-2 weeks. The exact time may vary depending on the patient’s own condition. The possibility of self-healing exists because the new coronavirus infection is a self-limiting disease, and if the patient’s autoimmunity is strengthened, the body’s immune function comes into play and specific antibodies are produced, thus allowing the patient to gradually recover. Even mild cases are contagious and may pose a risk to family members, friends and others around them. Therefore, if symptoms related to neocoronavirus infection appear, early isolation and treatment measures should be taken. During the home isolation period, patients with mild NCAI can eat fresh vegetables and fruits and consume enough energy, such as dark vegetables, seasonal fruits, fish, shrimp, meat, eggs and soybeans. Drink a sufficient amount of water a day, but note that not drinks, milk tea and other drinks, but plain water or light tea water. Ensure enough sleep i.e. have about 8 hours of sleep a day. Keep a stable mind, don’t be too nervous and anxious, you can do some relaxing recreational activities, such as reading books, listening to music and other activities you like. All of these measures can help to relieve the condition of patients with mild disease. However, not all people can be cured by themselves, so do not delay the treatment because the new coronavirus infection is self-limiting. If you are weak and have symptoms such as fever, dry cough and weakness, you must go to the hospital in a timely manner with good protection for yourself to achieve early detection, diagnosis, treatment and isolation to avoid aggravation or spread of the disease. You need to seek medical attention in time and actively cooperate with the doctor’s treatment measures in order to achieve a cure.
