I am not a doctor but I have some basic medical background. Viral Infections DO NOT have cures, you can only immune yourself against a certain viral infection through a vaccine. If you have not been vaccinated earlier and you get infected, there is nothing you can do except to let your immunity system fight the virus & develop the anti-bodies so that you don't get infected again in the future.
Any viral cure will work on killing the cells the virus is occupying, so essentially it's damaging to the body with unknown side effects.
Viruses occupy certain types of body cells, so recovering from a viral infection means that those cells must be killed. Luckily, most cells in the body can be renewed (Except when the damage is so large that your dead cells won't be re-created, as in the case of Hepatitis C in late stages, which attacks the liver cells, so you essentially need a liver transplant, otherwise, death is just a matter of time).
So the talk about finding a cure for COVID-19 or any virus type is just hocus pokus.
