There is no anti-Covid-19 drug globally accepted for treatment, but many drugs are under investigations. About 16 trials of antivirals are under development (6 march 2020).
Antiviral drugs are difficult to find, because of the cell-parasitic nature of viruses. It has been long to get efficient drugs against HIV or Hepatitis C.
COVID-19 vaccine may arrive before we get efficient antivirals.
