Asymptomatic infection is defined as a positive nucleic acid test for the new coronavirus without symptoms such as fever or cough. Asymptomatic infected patients are defined as those who have positive nucleic acid test results, but do not have any obvious symptoms, and do not have any other discomforts, and can only be defined as asymptomatic infected patients. This type of infected person can be cured after intensive isolation and symptomatic supportive treatment, and generally will not cause sequelae. After the recovery of asymptomatic infected patients, they should be isolated and observed in daily life. During the observation period, they need to pay attention to their bodies to see if there are any abnormal symptoms again, such as fever, cough, difficulty in breathing, etc. If such symptoms appear, they should seek medical treatment in a timely manner in order to avoid recurrence, and pay attention to nutritional intake in general, and to enhance their body’s immunity through exercise. If the patient recovers with fever, dry cough and other symptoms, it is recommended to standardize the treatment as soon as possible to reduce the adverse phenomena.
