At the very least, mortality is not viewed the same as in western nations and that impacts the tracking and reporting. I would expect reported infections and specific deaths to go down as a country's wealth decreases.
tl;dr: third world gonna third world.
I'd be interested to see what a rigorous peer-reviewed article came up with to explain it.
