Fig 1 Symptoms of infection between the sexes
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).
