The map is from Ivermectin Safety Profile by David Archibald. Here’s what the different colours mean.
In the graphic above, the blue area shows the countries of Africa that distribute ivermectin once or twice a year for the control of parasites. The brown area is the countries that don’t. The brown line is the daily deaths from Covid per one hundred thousand people in those countries. The blue line is the same for the blue area — which is enjoying a far, far lower Covid death rate. A lot of the poor and backward countries of South America, Africa and Asia have now approved ivermectin for Covid.
So the question is why haven’t the rest of us done the same? When we finally work it out, I suspect there won’t be enough lampposts to go around.
