  • WHO declared a Public Health Emergency of International Concern (PHEIC) on 18 May 2026 — one of the highest-level global health alerts issued by the UN health agency.
  • Latest WHO situation report: 676 total reported cases across DRC (Ituri province) and Uganda, with 132 deaths and 668 contacts identified.
