This week, U.S. first lady Melania Trump has been visiting Africa. Even though she has visited Ghana
, Malawi, Kenya and Egypt, her husband
has not visited the continent since he became president. The following infographic is based on a Quartz analysis
of Office of the Historian data
and it shows that Trump isn't alone in neglecting Africa. Out of the 54 countries on the continent, only 16 have been visited by a sitting American president, meaning over 70 percent of African nations have never played host to a U.S. presidential visit.
