With more than 3,000 cases and 2,000 deaths recorded since the outbreak was declared last summer in Congo, the Ebola outbreak has reached another troubling milestone, according to the World Health Organization.
Though the vast majority of infections remain in the nation’s North Kivu province, the virus has spread to neighboring South Kivu province and the transit hub of Goma, on the border of Rwanda.
The region’s political instability, sporadic violence, limited infrastructure and mistrust in vaccines are obstacles to address in ending the outbreak.
