Overview

• WHO now counts 47 confirmed cases with 25 deaths, and reports about 10 additional probable cases and deaths.
• Transmission remains concentrated in Kasai’s Bulape, Mweka, Mushenge and Kakenge health zones, which are difficult for responders to access.
• Ring vaccination with the Ervebo vaccine is underway, with roughly 1,500 contacts and health workers immunized and about 4,000 doses prepositioned in Bulape, as DRC draws on a 2,000‑dose national stockpile.
• CDC says it has deployed two epidemiologists and a senior advisor, is coordinating with the White House and WHO, and is supporting epidemiology, case tracking, laboratory testing and infection control.
• Genetic evidence indicates the virus differs from recent strains, suggesting a new animal‑to‑human spillover, while experts attribute the high fatality to late presentation and limited local care.
