Usually, patients should be sent to the fever clinic for pre-testing and triage when the temperature reaches 37.4 ℃ or higher to rule out novel coronavirus infection. If the blood is monitored in the fever clinic and the serum is positive for viral nucleic acid or a highly homologous gene series, the patient should be isolated for treatment and diagnosed with novel coronavirus infection. Because of the early symptoms of novel coronavirus infection, the body temperature is predominantly low to moderate fever and the fever is not very pronounced. When the disease progresses further for about a week, the body temperature exceeds 38.3 ℃ and does not subside, and there is no effect with antipyretic drugs, then the symptoms of respiratory distress also increase, and the patient turns from a light to a heavy patient. Therefore, in patients with early suspected novel coronary pneumonia, it is important to monitor the body temperature, control the symptoms, and provide timely symptomatic treatment.
