Six months after it was declared, the Ebola outbreak in the Democratic Republic of Congo remains out of control, with containment efforts faltering. The outbreak has recorded more than 11,000 cases, and nearly half of those infected have died, according to government data. This marks the deadliest of Congo's 17 Ebola outbreaks and is on track to surpass the death toll of the 2014-2016 West African outbreak.

Basic containment measures such as contact tracing and isolation have proven inadequate, casting doubt on authorities' ability to halt the spread. Experts suggest there is little chance of bringing the outbreak under control within the next year. The virus was circulating undetected for an extended period before the outbreak was officially announced in mid-May, by which time 43 deaths had already been recorded. It has since spread to eight of Congo's 26 provinces, moving at a speed aid groups have compared to wildfire, with new hotspots continually emerging and straining the healthcare system.

Community transmission remains high, with the Africa Centers for Disease Control and Prevention reporting that 80% of new cases are detected outside of official surveillance. A third of deaths occur at home or within communities, where burials and other rituals are often conducted without specialist supervision, increasing the risk of transmission.

Health workers have gone on strike multiple times over months of overdue pay, at times leaving confirmed patients without treatment. Aid groups have also raised concerns about the management of the response, with the Africa CDC questioning the whereabouts of more than $700 million in Ebola aid. Doctors Without Borders (MSF) has noted a "troubling disconnect" between the resources mobilized for the response and what is reaching patients, frontline workers, and communities.

Children are particularly vulnerable, especially those with pre-existing conditions like malnutrition. Most affected children have not received specialized care, contributing to high death rates. UNICEF data indicated that children accounted for 35% of recorded deaths through November 4, with children under five making up 21% of all deaths in that age group, and nearly 72% of infected children under five have died.

Health workers face difficult conditions, with Ebola prevention measures clashing with social and cultural practices. Since the outbreak began, health workers have been attacked, some fatally, adding to the dangers in an already volatile region where health facilities have also been targeted. The outbreak is concentrated in eastern Congo, particularly in Ituri and North Kivu, where communities are contending with both the epidemic and armed conflict from numerous rebel groups.

The rapid spread has fueled fears of wider transmission across Africa, with Nigeria, Kenya, and Uganda having confirmed cases, making this the most geographically widespread Ebola outbreak on record.
