Outbreak early warning: how many days earlier?
1000 simulated outbreaks in a 20-area district. Priora watches AI-tagged symptoms from kiosk intake every day. Today, an outbreak shows up only through lab-confirmed cases in weekly reports, and a quarter of those reports arrive late.

Lead time across outbreaks: days Priora alerted before lab-confirmed reporting
Priora is earlier in most outbreaks; slow-growing ones can still be caught first by lab reports (gray). It needs real kiosk coverage: below roughly 40% of care-seeking patients, the advantage disappears. That's why the pilot targets the district's largest OPDs.
Impact: one OPD morning, simulated
300 patients arrive over 4 hours to 4 doctors. The same synthetic patients go through today's single first-come line and through Priora. Only the process changes.

today: 5.7 h · 3.8 h saved
Critical patients jump the line, and the session ends 77 min earlier because fewer patients re-queue and doctors spend less time on paper files. Trade-off: GREEN patients wait longer (median 1h 8m → 1h 37m), still 100% within their 4-hour target, with a fairness rule promoting anyone past it.
