The duration of fever in neocoronavirus infection depends on the patient’s condition. For example, in mild patients, the fever may be normalized in 1-2 days or 3-5 days, and other symptoms will improve because it is a mild neocoronavirus infection, and in common patients, the clinical manifestations may be low or moderate fever, and the duration of fever may be 1-2 days to a week, but the overall duration of fever is not too long. In heavy or critical cases, especially in critical cases, where early viral infection is followed by respiratory failure and a bacterial infection is combined with the treatment process such as tracheal intubation, the fever may last longer. The duration of fever may be a very important indicator to judge the patient’s condition. If the patient’s body temperature returns to normal, the overall condition is improving, if the fever continues to be high, it means the condition is more serious, especially if the body temperature is as high as 39℃ for a long time, and the continuous 39℃ high fever may indicate that the patient’s condition will enter the severe type.
