Abstract
Background and Aim: COVID-19, a viral respiratory illness. In this review, we discuss issues such as the genetic structure, pathogenic mechanism, clinical characteristics, diagnosis, treatment, and prevention of COVID-19 based on the latest findings.
Materials and Methods: The Medline was searched for terms such as “Coronavirus” ،“ COVID-19” and “Respiratory infection”.
Findings: In December 2019, the unprecedented outbreak of pneumonia with unknown etiology began in Wuhan, Hubei Province, China. The cause was a new coronavirus, named COVID-19 by the WHO. This virus has high transmissibility and affects the lower respiratory tract. Research into the mechanism and treatment of COVID-19 is under way, and new information is being provided every day, some of which are contradictory. COVID-19 is a serious and dangerous infectious disease and a significant threat to the health of the world's population, and should be prevented from spreading rapidly.
Conclusion: Because the exact mechanisms of the disease have not been fully elucidated and specific drug or vaccine have not yet been developed for it, control is mainly based on the interruption of the transmission cycle.

Abstract
Background and Aim Coronavirus disease 2019 (COVID-19) is a respiratory disorder that can affect many body systems, including the hemostatic system. In this study, we aim to investigate the role of hemostatic system and the blood coagulation in COVID-19.
Methods & Materials In this review study, the articles were searched using the keywords COVID-19, Respiratory infection, and Coagulopathy in Google Scholar, PubMed, Google Springer and Science Direct databases.
Ethical Considerations Ethical principles in writing this article were observed in accordance with the guidelines of the National Ethics Committee and the Committee on Publication Ethics (COPE).
Results Many changes in the coagulation profile of infected patients were reported, including changes in the platelet count, fibrinogen/fibrin degradation product, D-Dimer, fibrinogen, prothrombin time, and activated partial thromboplastin time. With the increase in the number of patients with COVID-19, several studies found out the occurrence of thrombosis and coagulopathy in patients.
Conclusion Due to the increase in the occurrence of coagulation disorders in patients with COVID-19, the administration of anticoagulants is needed for their treatment; it can play an effective role in improving the prognosis of patients.
