Main Article Content
There has been extensive research on post-viral fatigue, and the present mini-review and commentary provides an overview of the effects associated with different infecting agents. Fatigue is not only a subjective state, rather it has an impact on our ability to carry out everyday functions, and its effect can be demonstrated using performance tasks. It is not surprising, therefore, that persistent effects of COVID-19 are observed, and the key features of Long Covid are reviewed here, Suggestions for further research which will provide a better understanding of Long Covid and provide a basis for prevention and management are also discussed.
