This is a web-based registry. After registration, physicians from hematology clinical centers and hospitals in Russia will receive access to the web platform for clinical trial management to fill in the online data collection form in a de-identified manner. This form includes questions about general clinical history of hematologic disease, manifestation, treatment, and the course of COVID-19, concomitant conditions, consequences on the hematologic disease, short-term and long-term outcomes. It will take approximately 10 min to answer the questions. Patients will be followed for 30 days after COVID-19 diagnosis and up to 6 months for hematologic disease outcomes and overall survival assessment.
