Physical and mental health
The cardiopulmonary endurance level after infection was significantly lower than that before infection (P<0.01), and that of males before and after infection was significantly higher than that of females (P<0.01). The better the cardiopulmonary endurance level after infection, the shorter the conversion time, and the cardiopulmonary endurance level after infection was significantly positively correlated with the conversion time (r=0.64, P<0.05).
Among all the interviewees who recovered from infection, 67.62% had no anxiety, 20.83% had mild anxiety, 7.11% had moderate anxiety, and 4.44% had severe anxiety. The GAD-7 score during infection was 3.70±4.82. The anxiety of women (3.92±4.97) was more serious than that of men (3.33±4.54, P<0.01). There was a significant difference between the number of symptoms and the score of GAD-7. The more symptoms during infection, the higher the score of GAD-7, that is, the more anxious the infected person was (r=0.224, P<0.01).
The sleep score after infection (8.27±7.05) was significantly higher than that before infection (4.17±4.97, P < 0.01), and there was no gender difference before infection (P=0.465). After infection, the sleep score of female (8.87±7.02) was significantly higher than that of male (7.25±7.00, P<0.01). There was a significant positive correlation between the number of symptoms and sleep quality of the infected (r=0.306, P<0.01). The more symptoms the infected showed, the worse the sleep quality (Fig 2).
