Abstract
Many contagious diseases, such as plague or cholera, played a role in changing the pathway of history. In this respect, although coronavirus was not as dangerous as novel diseases such as swine flu and Ebola, the spread and the power of coronavirus infiltration caused public fear across the world. Three viruses among coronaviruses have been epidemic during the recent years, including severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and COVID-19 or new coronavirus. Respiratory droplets transmit the coronavirus through direct and indirect contact, and it can be transmitted through the contact in the case of remaining, the infected person's secretion on the surface. Based on the conducted studies on the treatment of COVID-19 disease, there is virtually no cure or vaccine for coronavirus infections yet. Those infected with Covid 19 are quarantined to prevent the outbreak of this disease. However, the researchers carried out different studies to investigate the impact of the various drugs on this virus, which in this study, we will examine the outline of this disease and the other conducted studies.
