West Africa's Ebola virus epidemic
The 2014 Ebola outbreak devastated West Africa, killing more than 11,000 people over a two year period. One country that suffered was Sierra Leone.
The disease started in Guinea, but quickly spread to neighbouring countries.
Before May 2014, there had never been an outbreak of Ebola in Sierra Leone. By autumn that year, burial teams were struggling to keep up with the number of corpses that needed burying.
