As a result, an immediate treatment option in needed for this current situation. Although, several potent antiviral drugs, vaccines are under urgent investigation but no candidate found so far for SARS-CoV-2 virus. In this literature review we summarized all the latest research progress of the causative agent, pathogenesis, epidemiology, immune response, clinical characteristics, diagnosis, treatment, management of diseases, control, prevention strategies of COVID-19. | en_US |
