Sylvain Groulx, head of the CAR mission for Doctors without Borders, told the United Nations' Integrated Regional Information Networks, known also by its initials IRIN, the nation's health system was failing under the strain of violence.
"Health structures have been looted, the few qualified personnel have fled, drug supply and logistic means are non-existent or paralyzed and even worse is the population which flees violence by seeking refuge in the bush [and] does not have any access to the most basic of health care," he said in an interview published Thursday.
Melanie Wissing, a director with the Internal Displacement Monitoring Center, told IRIN about 10 percent of the 4.6 million people in CAR were displaced by violence.
