WHO’s 26-country Polaris II drill puts UAE outbreak readiness under scrutiny

World Health Organization (WHO) completed Exercise Polaris II on 23 April 2026, after 26 countries and territories tested outbreak response to a fictional new bacterium.

For UAE hospital, clinic and laboratory executives, the practical test is whether a facility can staff, report and coordinate across DHA, DOH or MOHAP in the first 24 hours.

What WHO tested

WHO said Exercise Polaris II, held on 22 and 23 April 2026, brought together 600 health emergency experts and more than 25 partner agencies. The exercise tested emergency coordination structures, information flows, policy coordination and workforce surge capacity under real-life conditions.

WHO said the scenario used a fictional bacterium. That matters for UAE operators because bacterial threats can pressure infection control, antimicrobial stewardship, laboratory capacity and isolation workflows at the same time.

The drill followed Polaris I, held in April 2025, which used a fictional virus. WHO said Polaris II used the Global Health Emergency Corps framework, published in June 2025, and the National health emergency alert and response framework, published in October 2025.

• 26 countries and territories participated, including Oman, Qatar, Jordan, Egypt and Yemen.
• 600 health emergency experts joined the simulation.
• More than 25 national, regional and global agencies tested technical and surge support.
• 2 WHO frameworks were put into practice.

Why UAE operators should act

The UAE was not listed among the participating countries in the WHO release dated 27 April 2026. The exercise still has direct use for licensed providers because DHA, DOH and MOHAP oversee communicable-disease reporting, emergency preparedness and infection prevention in their jurisdictions.

For COOs, the question is whether each facility can run an emergency operations structure for 48 hours without informal messaging. For CIOs, the test is whether surveillance, laboratory, bed-management and staff-scheduling systems can produce one operating picture. For medical directors, the risk sits in triage protocols, antibiotic policy, isolation decisions and clinical escalation.

UAE healthcare groups should treat Polaris II as a 2026 board-risk checklist. A major outbreak can reduce elective volumes, raise overtime costs, expose infection-control failures and trigger regulator scrutiny across multi-site networks.

Checks to run before the next alert

Facilities should test four areas before the next regional alert: emergency command activation, regulator notification routes, staff surge rosters and digital reporting. Large groups with assets in Dubai, Abu Dhabi and the Northern Emirates need separate escalation maps for DHA, DOH and MOHAP, because site teams need the right reporting channel before an outbreak starts.

WHO said Exercise Polaris II is part of HorizonX, its multi-year simulation programme. The next signal for UAE executives is whether more GCC countries join future drills after 2026, which would put more attention on cross-border outbreak data, workforce deployment and AI-supported emergency planning.

The number to remember is 2 days. Run a 2-day internal drill in 2026, document the failure points and assign owners before DHA, DOH or MOHAP asks the same questions during a real event.
