An Ebola outbreak is expanding in the eastern Democratic Republic of Congo as contact-tracing coverage falls and burial teams face attacks.
The deteriorating situation in Ituri province threatens to outpace the ability of health workers to isolate the virus, potentially leading to a wider regional epidemic.
Health officials have recorded 344 confirmed infections [1] and 60 confirmed deaths [2]. The scale of the crisis may be larger than confirmed figures suggest, with more than 1,000 suspected cases [3]. In a single 24-hour period, responders recorded 26 additional suspected deaths [4].
Containment efforts are struggling in areas more than 100 miles from the gold-mining town of Mongbwalu [5]. A primary driver of the spread is the collapse of contact-tracing. While some reports indicate that fewer than 40% of known contacts are being tracked [6], other data suggests coverage has dropped to about 20% of identified contacts per day [7].
This gap in monitoring allows the virus to spread undetected through communities. The situation is further complicated by insecurity in the region. Burial teams, who are essential for preventing transmission from deceased patients, have been targeted in attacks [8].
These attacks create a dangerous cycle where safe burials cannot be performed, increasing the risk of infection for family members, and community residents. The combination of violence and failing surveillance has left health workers unable to keep pace with the virus's movement across the province [8].
“Contact-tracing coverage has fallen to fewer than 40% of known contacts.”
The failure to maintain contact-tracing and the targeting of health workers indicate a breakdown in the community-trust model required to stop Ebola. Because the virus relies on close contact for transmission, the inability to track 60% to 80% of contacts means the outbreak is likely moving faster than the official data can capture, shifting the response from containment to crisis management.
