Seriously though, it does have a higher rate of infection in impoverished regions without the resources or knowledge to properly deal with an outbreak. Also, many African traditional burial rituals involve handling, washing, and touching the dead body, which brings people in contact with the bodily fluids and thus infection. So yeah, there is a correlation with poor African communities.
The Ebola virus exists in certain animal species found in an impoverished region of Africa. On rare occasions a human is infected by an animal carrying the virus leading to an outbreak of the disease. Almost everyone who lives in this region is black, thus most of the victims are black.
