When talking about development, which most definitely affects how many disease and what type of disease a country gets, what is taken into consideration? According to UN's HDI (human development index), the things taken into consideration are life expectancy, the way you live life, and illiteracy rate are what determines how develop a country is.
Lets look at those aspects in Africa. In Africa, the life expectancy varies from country to country, but it is said that the average life expectancy is somewhere between 40-60. This is very low compared to the 70s of other countries. Living in Africa, is no walk in the park, they have little hospitals, dirty water, and few medical buildings. Living is not easy. The illiteracy rate for the countries in Africa vary widely as well, but the average seems to be between 24% to even as much 63%.
According to UN, with all these poor conditions in Africa, they are not developed. This makes it hard for them to do things, and help their people. Things can change, but it isn't all that easy, but change is good and like it is now, it is very needed.
