Dunno about the prevelance, seems like it was maybe three or four men in every platoon. They’d have shakes and chills for maybe three days, and some ran fevers.
I was young and strong, and not one of the ones who got sick.
But we were all young and strong, so side effects are probably much more worrisome for people not in military shape and with a lot of years of accumulated living.
Probably any pharmaceutical site will give you the medical information if you look up hydroxychloroquine.
I wonder where you on chloroquine — that sounds more like the side effect profile. Hyrdoxycholorquine has very few side effects according to the people for whom I have given the drug. I have no experience with chloroquine, but I am under the impression that it was a rougher drug in terms of side effects.
This is one of the better posts I’ve seen about HCQ in the military.
