A novel coronavirus (SARS-CoV-2) is now rapidly spreading throughout the world. Patients undergoing long-term in-center hemodialysis (HD) are highly vulnerable given kidney failure, comorbidities, and the need for frequent visits to a dialysis facility.


A total of 610 patients on maintenance HD at DaVita clinics in 6 countries were tested for presence of infection with SARS-CoV-2 using polymerase chain reaction (PCR) between March 28 and May 18. Of these, 115 HD patients (19%) were positive. Information up to May 25, 2020, show that 44 patients have recovered. Clinical symptoms during infection with SARS-CoV-2 are reported from these 44 recovering survivors (Germany 13 patients, Poland 12, Portugal 12, Colombia 2, Saudi Arabia 3, and Malaysia 2) and classified into 4 categories: no symptoms, mild, moderate, or severe symptoms. Hospitalizations and time to recovery were also analyzed. Statistical comparisons were made using Chi-2 analysis and Kruskal-Wallis tests.


Of the 44 patients recovering from COVID-19, 22 patients were ≥70 years and 9 patients were >80 years. Symptoms in relation to age, hospitalization, and time to recovery are shown below.


The majority of HD patients (66%) who recovered from COVID-19 had no or mild clinical symptoms during the infection. There were no significant differences in the occurrence of symptoms from SARS-CoV-2 in relation to age, hospitalization, or time to recovery. Additionally, old and frail HD patients with confirmed COVID-19 may have mild symptoms of the disease.
