Why is Africa facing such a disease crisis?

a) Africa has a population that is highly susceptible to disease.
b) Africa has 14% of the world's population, 25% of local disease burden, but only 1.3% of global health workers.
c) Africa is experiencing climate change at a faster pace than the rest of the world and therefore disease is spreading faster.
d) African citizens do not believe in modern medicine.
