Coagulation Dysfunction And Hematological Changes In 633 Patients With Covid-19

Background: A previously unknown beta-coronavirus was discovered through the use of unbiased sequencing in samples from patients with pneumonia. The virus was named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by the international committee for the classification of viruses (ICTV). The disease caused by this virus was named as coronavirus disease 2019 (COVID-19). In addition to pulmonary manifestations, hematological changes such as lymphocytopenia, thrombocytopenia, and coagulation dysfunction can also be found in COVID-19 patients, and the mechanism is still unclear.
