Chloroquine is still widely used in Africa, along with Fansidar, because mefloquine and Malrone are too expensive.
You are right that chloroquine resistance is widespread, but, as they say, “TIA” (this is Africa), lots of bad things or things that don’t make sense happen all the time.
Agree it is still used. Also agree about TIA! (Same in SE Asia where resistance has a longer history.) My understanding is it is mainly used by locals as a cure (in conjunction with artemisinin), not as a preventative. I could be wrong on that, of course.
I am skeptical, though, that a huge percentage of the population is popping HCQ every day. Am I wrong on that? I am open to correction! I just wonder where the truth lies.
