The researchers at the University of Vienna, Austria, have now presented new evidence of triggers for fatigue following SARS-COV-2 infection. The team of researchers showed that an exaggerated anti-inflammatory response is likely to be responsible for long Covid syndrome (LCS). The study has been published in "iScience".
