African health authorities have been urged to mount an immediate, co‑ordinated response after fresh cases of the rare Bundibugyo Ebola virus were detected in Kenya and Nigeria, experts say. The appeal follows a long-running outbreak in the Democratic Republic of Congo (DRC) that has produced large numbers of infections and deaths.
Outbreak stretches across borders
Since a DRC outbreak was declared on 15 May, official counts have recorded 9,552 confirmed infections and about 4,600 deaths, according to reporting from health specialists. Four African countries have now registered cases linked to the strain: the DRC, Uganda, Kenya and Nigeria, while France reported one imported case that was contained in June.
| Country | Reported cases | Reported deaths |
|---|---|---|
| Democratic Republic of Congo | 9,552 | ~4,600 |
| Uganda | 20 | 2 |
| Kenya | 9 | Not specified |
| Nigeria | 1 | Not specified |
Calls for regional leadership
Misaki Wayengera, who formerly chaired Uganda’s ministry of health scientific advisory committee on epidemics, told SciDev.Net that the appearance of cases outside the DRC indicates containment efforts there have been overwhelmed. He warned that persistent insecurity and community distrust in eastern DRC have complicated early detection and response.
“These cases popping up in Nairobi and Nigeria should serve to wake up the African Union and the East African Community, to make a deliberate effort to put out the fire in the DRC,”
Wayengera urged collaboration between regional bodies and the DRC government to reduce cross‑border transmission by linking security, epidemiology and basic humanitarian support. He framed the problem as not only a health emergency but one bound up with wider instability in affected areas.
Experts urge measured action, not panic
Other public health figures stressed the need for coordinated cross‑border work while cautioning against alarm. Githinji Gitahi, chief executive of Amref Health Africa, described the current situation as calling for cross‑border co‑ordination, not alarm. He noted that the nine Kenyan cases formed a single cluster, with no confirmed community transmission and multiple negative laboratory tests reported in the investigation.
- Immediate priorities: strengthened surveillance at borders, rapid sharing of case data, and harmonised contact tracing between neighbouring states.
- Operational challenges: insecure terrain, community mistrust and constrained health infrastructure in eastern DRC impede rapid response.
- Vaccine and treatment: the Bundibugyo strain currently has no approved vaccine or specific antiviral licensed for use.
Context and limitations
Publicly available figures show significant mortality in the DRC outbreak, but reported numbers may understate the true scale where access is limited and security concerns restrict data collection. Experts caution that while imported and clustered cases outside the DRC heighten concern, they do not necessarily signal widespread community transmission in those countries.
It is also important to note the current lack of licensed medical countermeasures specifically for the Bundibugyo variant. That gap increases reliance on classical outbreak control measures — rapid case identification, isolation, contact tracing and supportive clinical care — and on cross‑border collaboration to prevent further spread.
Regional coordination mechanisms such as the African Union and the East African Community are uniquely positioned to facilitate joint action, but doing so will require logistical, political and security engagement with national authorities in affected areas.
The situation remains fluid. Effective response hinges on transparent reporting, sustained international engagement, and efforts to address the complex security and social factors that have frustrated containment in parts of eastern DRC.
