AB The  African  continent  is  the  second  largest  continent  in  the  world,  at  11.7  million  miles  squared,  which  is  20.4%  of  the  Earth’s  total  land  surface.1  Fittingly,  it  is  also  the  second  most  populous  continent,  with  853.6  million  inhabitants,  which  is  14.72%  of  the  world’s  human  population.1  The  continent  is  divided  into  54  recognized  countries,  and  the  average  life  expectancy  at  birth  is  58  years.2a  There  are  six  African  countries  that  lie  directly  on  the  equator,  and  this  has  implications  on  the  inhabitants’  exposure  to  ultraviolet  (UV)  rays.  The  Nile  River  is  the  longest  river  in  the  world  and  runs  a  course  of  4.132  miles  through  Africa,  providing  a  valuable  source  of  nourishment,  but  at  the  same  time  acting  as  a  breeding  ground  for  transmittable  skin  diseases  in  certain  regions.2  This  continent  is  considered  by  most  paleoanthropologists  to  be  the  oldest  inhabited  place  on  Earth,  with  many  considering  Africa  to  be  the  area  where  the  human  species  originated.1
