Kenya is among the countries that host a very high number of refugees in relation to its population. With Kakuma and Dadab it operates two of the largest refugee camps in the world, where hundreds of thousands of refugees from Sudan, Somalia and other war-torn countries live for decades in a semi-arid region. More than half a million Somali refugees live in the country. The project in which vivo is cooperating tries to develop and evaluate adapted psychiatric treatment strategies that address PTSD, substance abuse and severe psychotic disorders.
