The time it takes for a positive case of the new coronavirus to become negative varies from person to person, with most cases becoming negative within a week or so, while more severe cases may take several weeks to months, depending on the patient’s condition. The new coronavirus is mainly spread by droplet transmission and contact transmission, and patients will have symptoms related to respiratory tract infections. In some mild cases, only fever and dry cough occur after infection, and the symptoms are relatively mild, usually turning negative in a week or so. In some severe cases, symptoms such as respiratory distress and hypoxemia may occur, and recovery is slower, taking about a month in severe cases. For some patients whose symptoms progress to severe symptoms such as acute respiratory distress syndrome and septic shock, the time to turn negative will be further lengthened, even to several months. After the new coronavirus becomes negative, you should not let your guard down, and seek immediate medical attention if any discomfort occurs to avoid a relapse of the disease.
