Look at the numbers for Sierra Leone.
Cases of 14,124 and deaths of only 3,956, (28%) versus Guinea’s rate of almost 67% dead.
2014 Sierra Leone 14124 3956 28.0
2014 Guinea 3814 2544 66.7
Difference is probably because of different burial and funeral practices. In Uganda and Congo they typically hug the dead bodies at the funerals.........
