Abstract

SARS-CoV-2 causes primarily respiratory tract infection, but can also affect hematopoietic and immune systems. Quantitative and qualitative changes in lymphocytes, neutrophils, monocytes and platelets, are reported in infected patients. These changes are related to the severity of the disease. Lymphopenia is the most common finding in adult patients infected with SARS-CoV-2, while it is much less common in children. Leukocytosis can be detected in patients with severe infection, but rare in patients with mild to moderate infection. Thrombocytopenia or thrombocytosis can also be seen in accordance with the clinic. Dysplastic morphological changes in neutrophils and platelets can be detected in peripheral smear of patients.

Keywords: COVID-19, Hematology, lymphocyte, Neutrophil Thrombocyte
