35%chance, per Kāla▲ 7 pts since the last update

Why

Base‑rate: Historically, WHO has declared Ebola outbreaks contained within 2–3 months after the last confirmed case when swift isolation and contact‑tracing succeed. Latest evidence: Nigeria identified its first case on 20 Oct 2026; authorities have isolated the patient, begun aggressive contact tracing, and the Africa CDC is coordinating a regional response, suggesting the chain of transmission could be broken quickly.
