Hematological changes in patients with COVID‑19 (Review)

In December 2019, an emergence of pneumonia was detected in patients infected with a novel coronavirus (CoV) in Wuhan (Hubei, China). The International Committee on Taxonomy of Viruses named the virus severe acute respiratory syndrome‑CoV‑2 and the disease CoV disease‑19 (COVID‑19). Patients with COVID‑19 present with symptoms associated with respiratory system dysfunction and hematological changes, including lymphopenia, thrombocytopenia and coagulation disorders. However, to the best of our knowledge, the pathogenesis of COVID‑19 remains unclear. Therefore, understanding the mechanisms underlying the hematological changes that manifest during COVID‑19 may aid in the development of treatments and may improve patient prognosis.
