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.
