**3.3 Antiviral drugs**

Fluvoxamine, Umifenovir, camostat, ritonavir, Famotidine, Nafamostat, Lopinavir, hydroxychloroquine and chloroquine are drugs that are testing for medication of COVID-19. The treatment for SARS-CoV-1 and the Covid, which induce respiratory disorders for the Middle East, was successfully proved in vitro tests. However, there was no testing that confirmed that equal SARS-CoV-2 activity component. Nafamostat and camostat are antagonists of serine proteases. Camostat was already reported to prevent SARS-CoV entrance by acting as a researcher and serine protease inhibitor TMPRSS2 suggest together camostat, and nafamostat may inhibit SARS-CoV-2. Russia and China have licensed for use only as Umifenovir, and this is a tiny prophylactic indole derivative compound for influenza A and B viruses. Thiazolidine is Nitazzoxanide used in parasitic, bacterial and viral contamination as a viable enemy of an infectious disease. Several bio-informatics approaches can be used in detecting the sequence of the virus [7]. Scientists are also working to counteract potential "cytokine storms" in some patients that cause lung harm and severe respiratory discomfort. As stated early, for covid-19, there is no vaccines or drugs for the treatment. Hence some methods may predict this disease and take treatments to reduce its severeness and stop spreading to other persons. Some of them are discussed below.
