Conclusion
Consequently, the SARS-CoV-2 virus is spreading by leaps and bounds all over the world. The prognosis of the disease may vary depending on the nature of a person’s immune system. In this study, where hematological and inflammatory characteristics of peripheral blood were analysed, it has been shown that increased ferritin and D-dimer levels and decreased lymphocyte count are important factors affecting the duration of hospitalization for COVID-19 infection. Moreover, we point out low neutrophil count and MPV level and high platelet count and ferritin levels during the course of the disease, so these parameters can be used as prognostic indicators of the disease.
