Antivirals are notoriously expensive. How much are the ones cited?
I don’t know, but there is one company that makes the generic cocktail relatively cheap. But they would only be used on those that cannot recovery themselves (two-precenters). Basically it is used for HIV treatment and they almost give it away as part of their global mission.
AV aren’t in much use for anything but HIV and these are $14 to 20k per cycle in US or $400k lifetime cost.
I understand why Russia or Thailand with under a dozen cases might use it on coronavirus now but not the poorer nations with thousands infected.
