I actually wonder that too.
My impression is that malaria was wiped out in the rich world by methods that we now deny to Africa, like DDT.
I also believe malaria is a human only disease, so if you cure all sick humans fast enough, the disease dies out, and you're left with mosquitos that only suck blood and are annoying.
I suspect the problem with malaria drugs is not producing them at a factory, but getting them reliably into all sick patients in places where there aren't even doctors or roads.
Anyway, you claim this is a real solution: Is anyone actually ready to do this for real? If not, it's not a real alternative to the gene drive.
