In December 2019, coronavirus disease (COVID-19) due to infection with the novel SARS-CoV-2 virus began to break out. Hemodialysis patients are at high risk because of the co-morbidities. We report the clinical and biological characteristics of two patients who developed COVID-19 infection in our dialysis center in Donka National Hospital. None of the patients had contact with an infected person. The age was 38 and 54 years. The symptoms common to both patients were: fatigue, diarrhea, fever. Lymphopenia was present in both patients. None of them had a chest X-ray or chest scan because they were positive for the test before admission.
