It seems plausible that a near term cocktail of drug treatments might halve the fatality and halve the hospital times for coronavirus. This is just assuming the Remdesivir results could be improved with some other anti-virals or other drugs.
The preliminary data showed that the time to recovery was 11 days on remdesivir compared to 15 days for placebo, a 31% decrease. The mortality rate for the remdesivir group was 8%, compared to 11.6% for the placebo group; that mortality difference was not statistically significant.
Doctors have determined that a 5-day treatment with Remdesivir is as effective as 10-days. This means twice as many patients can get Remdesivir.
