Immune signature discovered for Long Covid

Severe covid 19 disease is characterized by excessive immune and inflammatory processes in the body. Conversely, long covid syndrome is likely to have a strong anti-inflammatory immune status. Scientists have now found this out with extensive blood plasma analyses of vaccinated persons without subsequent disease, persons with completely survived covid 19 infection and long covid patients. The scientific work of the team led by study director Christopher Gerner from the Faculty of Chemistry at the University of Vienna and researchers from MedUni Vienna has now been published as a pre-proof in the open access online journal "iScience". -Since the onset of the pandemic, it has also become apparent that not all patients recover fully after SARS Cov-2 infection. Initially, the symptoms of affected individuals were mainly attributed to psychological factors such as anxiety and stress. It is now recognized that chronic persistent covid-19 symptoms following acute infection represent a new somatic condition called post-acute covid-19 syndrome (PACS) or long covid-19 syndrome-, the study states.
