Yellow Fever first originated in Africa in the early 1600's. It was transmitted by mosquitoes to primates and humans. It shows that Africa has it harder because they are a 3rd world country and it is harder to get vaccines to prevent diseases.
If a major outbreak happened, the country would get even worse. The fighting would get more intense and people would take matters into their own hands. Economically, businesses would go out of business and many people would go bankrupt.
