It is not accurate to say how much higher the body temperature will be quarantined. However, based on the current cases of novel coronavirus pneumonia, home isolation is recommended if the body temperature is higher than 37.3 degrees Celsius. If the temperature exceeds 37.3 degrees Celsius for more than seven days, and there is a history of living in an infected area, a history of travel, or close contact with a confirmed patient, you need to go to a designated hospital immediately, and promptly carry out medical isolation, although the new type of coronavirus pneumonia has the symptom of fever, but there is no symptom of the new type of coronavirus pneumonia, not based solely on the temperature of the number of degrees to determine whether or not the infection. Some patients with mild cases of novel coronavirus pneumonia may only have a low-grade fever and mild malaise without symptoms of pneumonia, which should be recognized accordingly. Some children and newborns may have atypical symptoms, such as low-grade fever, vomiting, diarrhea and other digestive symptoms, or only mental weakness and shortness of breath without cough, which should be identified accordingly. If the fever is not caused by an infectious disease, it can not be isolated.
