Conclusion
This study confirmed that some symptoms lasted for a long time in individuals who recovered from COVID-19 infection, fatigue was a common symptom of infection, and people’s cardio-pulmonary endurance, psychology and sleep were affected during the infection. The symptoms of sedentary and irregular exercise people lasted for a long time, but the clearance time still needs further research. COVID-19 infection continues to be a health challenge in the 21st century, and more in-depth research is needed.
