Despite the presence of UN peace-keeping forces, Haiti's capital, Port-au-Prince, has been subject to widespread violence since Jean Bertrand Aristide's departure in February 2004. A few months later, in September 2004, MSF set up a program in Saint Joseph's Hospital, close to the cities most dangerous neighborhoods. Patients include victims of urban guerilla warfare as well as victims of accidents and domestic violence. MSF has also opened a rehabilitation centre where patients can receive treatment following surgery.
