WHAT IS HAPPENING · SUMMARY OF WHO DISEASE OUTBREAK NEWS

As of 23 September 2026, the DRC has reported 7890 confirmed cases including 3799 deaths, giving a crude CFR of 48.1%. Since the previous Disease Outbreak News on 11 September 2026, an additional 1133 confirmed cases and 532 confirmed deaths have been reported in the DRC. The outbreak has expanded to 63 health zones across seven provinces, including a newly affected province, Sud Ubangi, increasing the risk of cross-border transmission.

FOR THE GENERAL PUBLIC

The continuously high CFR and high rate of deaths occurring in communities highlight persistent challenges in timely case detection and access to early and adequate patient care. Geographic expansion to a province bordering South Sudan increases the risk of cross-border transmission.

FOR TRAVELLERS

DO NOT TRAVEL to Ituri Province DRC (CDC Level 3). Avoid non-essential travel to Uganda (CDC Level 1). US entry ban for anyone from DRC, Uganda or South Sudan within 21 days. Seek immediate medical attention if symptomatic after visiting affected areas.
