In all respondents, the average time of overcast was 7.46±3.18 days, with a minimum of 2 days and a maximum of 39 days. 924 people (91.21%) had fever during infection, 15.91% had fever temperature of 37.3-38℃,49.57% had fever temperature of 38.1-39℃, 30.74% had fever temperature of 39.1-40℃, 3.46% had fever temperature of 40.1-41℃, and 0.32% had fever temperature above 41℃. The average number of days from fever to fever was 2.43±1.24. Eighty-nine people (8.79%) did not develop fever during infection. Taking age as an independent variable, it was observed that the duration of symptoms in the population after COVID-19 turned negative was significantly correlated with age, and had statistical significance with the duration of some symptoms (Table 2).
