COVID-19 caused by SARS-CoV-2 has lead to a global pandemic already affecting over 3.5 million persons with more than 243,000 confirmed deaths [1]. Early reports from China indicate that persons with cancer are more susceptible to SARS-CoV-2 [2]. However, there are no data on the prevalence of COVID-19 in different types of cancer, including chronic lymphocytic leukemia (CLL).
