The World Health Organization (WHO) has highlighted the immense challenges faced in executing contact tracing amid the Ebola outbreak in the Democratic Republic of the Congo.
This crisis is exacerbated by ongoing regional conflicts, mining activities, and intricate population dynamics, which have rendered containment efforts remarkably difficult. WHO Director-General Tedros Adhanom Ghebreyesus emphasized that current conditions are severely obstructing effective contact tracing and containment, essential methods for managing the Bundibugyo strain, the less common variant responsible for this outbreak.
“In many impacted regions, health facilities struggle to function effectively due to insecurity. Furthermore, deteriorating road conditions hinder the distribution of goods and critical humanitarian aid,” Tedros said in a recent briefing.
These challenges have significantly hampered the ability to track and monitor those in contact with confirmed and suspected cases. Data from the DRC Ministry of Health around mid-to-late May 2026 indicated that, of the over 1,600 identified contacts, health workers managed to follow up with only 21 percent on a typical day.
Without approved vaccines or specific therapeutic options available for the Bundibugyo strain, the reliance on conventional public health interventions, such as case isolation and community engagement, has only increased. WHO has repeatedly called for strengthening these essential activities despite the prevailing hardships.
The outbreak was officially announced by DRC officials on May 16, following laboratory confirmation of the Bundibugyo virus in samples from cases identified in Ituri Province. Initially, reports confirmed eight laboratory-positive cases, 246 suspected cases, and 80 suspected deaths within health zones like Bunia, Rwampara, and Mongbwalu.
The virus has also been detected in Uganda among travelers from the DRC.
As of late May, the latest data from health authorities in both DRC and Uganda indicate a concerning escalation. The DRC reported around 1,077 suspected cases, 121 confirmed cases, along with 246 suspected deaths and 17 confirmed fatalities.
On the mark, Uganda registered a handful of linked cases, including about seven confirmed instances and at least one death. No other nations have reported confirmed cases related to the outbreak as of now, although several neighboring countries have restricted travel from the DRC.
