Guinea, Liberia, and Sierra Leone are all poor countries with limited access to health care.

Additionally, http://en.wikipedia.org/wiki/Water_supply_in_Sierra_Leone opens with "Water supply in Sierra Leone is characterized by limited access to safe drinking water."

The parent made no statement that all of Africa is so limited, only that the outbreak was in Africa. The countries most affected by the outbreak were correctly described.
