Gastrointestinal manifestations of long-term effects after COVID-19 infection in patients with dialysis or kidney transplantation: An observational cohort study

Figure 3 Illustration of the proposed new nomenclature for clinical syndromes following post-corona virus disease 2019 infection. We propose that the term post-acute-corona virus disease 2019 (COVID-19) syndrome should describe illness occurring within 90 d from the onset of COVID-19 infection. Chronic COVID-19 syndrome (CCS) would then be a modified classification that refers to the clinical syndrome thereafter. By contrast, the term Long-COVID syndrome should be reserved for patients showing CCS lasting for at least six months. In the case of severe symptoms, the investigation and corresponding treatments should be addressed at 60 d to prevent serious CCS. Long-COVID: Prolonged symptoms after corona virus disease 2019.
