Newsletter Edition #346 [The Files Brief]
Readers,
We bring you a quick update on the outbreaks of Ebola and the Hantavirus, from a briefing by the World Health Organization, yesterday, on May 15, 2026.
At the cusp of the World Health Assembly, when 192 member states of the World Health Organization gather in Geneva starting Monday, these outbreaks are as much a sombre reminder of the fragility of health, as they are about the importance of collective efforts to safeguard health.
My colleague Kavishalinie brings you this edition.

Key Takeaways:
Ebola Outbreak in the DRC
- Location & Scope: A new outbreak is confirmed in the Ituri province, northeastern DRC, with 13 laboratory-confirmed cases.
- WHO Response: DG Tedros said WHO has released $500,000 from the WHO contingency fund for immediate response, including surveillance, contact tracing, and laboratory capacity.
- Operational Challenges: The region is highly volatile with significant population mobility due to mining and cross-border trade, which increases the risk of transmission.
- Vaccination Status: Testing is underway to confirm the specific strain; while Zaire strain vaccines are licensed, protocols are being readied for experimental vaccines should they be required for other strains.
Hantavirus (Andes Virus) Global Response
- Current Count: 10 total cases (8 confirmed, 2 probable) and 3 deaths linked to the cruise ship MV Hondius.
- Transmission Risk: While human-to-human transmission has likely occurred on board, the global risk to the public remains low.
- Quarantine Measures: All passengers and crew are classified as high-risk; WHO recommends a 42-day quarantine due to the virus’s long incubation period.
- Scientific Investigation: Genomic sequencing by multiple global labs has found no changes suggesting the virus has become more transmissible or severe.
- Origin Tracking: Scientists are investigating if the virus was present in Ushuaia, Argentina, prior to the ship’s departure on April 1.
- Research: WHO and international researchers are establishing a “natural history study” through the WHO R&D Blueprint to better understand infection duration, infectiousness, and long-term virus detection.
