During the coronavirus disease 2019 (COVID-19) pandemic, hemodialysis patients constitute one of the most vulnerable patient populations as they have more significant comorbidities and need to visit healthcare settings frequently even under pandemic conditions. It was also largely demonstrated that hemodialysis patients have high mortality rates with severe to fatal disease due to COVID-19 during their initial hospitalization. Even though the functional decline and fatigue after severe infections are not novel entity, some long-term effects of COVID-19 has drawn attention with its prolonged effects even after discharge. A recent prospective, observational study of Carriazo et al provided the first evidence to compare long-term mortality rates of hemodialysis patients with and without COVID-19. Carriazo et al stated a hazard ratio of 3.00 for the mortality rates of hemodialysis patients over a one-year follow-up period after the COVID-19 diagnosis. They emphasized that the high mortality rates of hemodialysis patients with COVID-19 are not limited to the initial hospitalization period but also continue after discharge, especially the first three months. In the light of this study, it can be recommended that hemodialysis patients with COVID-19 should be monitored closely and continuously and hemodialysis patients should be prioritized for a vaccination against COVID-19 with close follow-up for their antibody levels.

showed that high mortality rates of COVID-19 in hemodialysis patients are not limited to the initial hospitalization but also continue in the first year after the diagnosis. In short, COVID-19 seems to have long-term consequences on hemodialysis patients with higher mortality rates not limited to the initial hospitalization period but also one year after the diagnosis. All infections tend to present more severely in hemodialysis patients due to comorbidities, drug regimens and, vulnerability than in other patient populations and COVID-19 is not an exception. COVID-19 is not the first pandemic and it will not be the last one. Future pandemics will also be threats to
