Ebola Outbreak in Eastern DRC Driven by Rare Bundibugyo Strain Expands to Uganda

Licensed vaccines and treatments do not protect against this strain, making rapid development of strain‑specific vaccines and therapies urgent.

Overview

  • The outbreak, declared in mid‑May, has produced several hundred confirmed cases (reported roughly 344–363) and about 60–62 confirmed deaths and has crossed into Uganda.
  • Early automated tests missed many infections because Bundibugyo differs from the common Zaire strain, but lab capacity has been scaled up and backlogs of samples are being cleared.
  • Contact tracing remains far below target at roughly 45%–46% of contacts followed and insecurity, attacks on burial teams and patients fleeing care are blocking access to communities.
  • WHO and partners are accelerating candidate vaccines and treatments while warning that funding shortfalls (WHO estimates $115 million for three months) and blanket travel restrictions are disrupting supplies and logistics.
  • If containment fails, the region’s high population movement, mining camps and displaced people could sustain transmission and force wider cross‑border public‑health measures, so watchers should track contact‑tracing rates, community access and progress in strain‑specific trials.
