Limitation: The INSP SitRep begins on 2026-05-14. All 21 health zones were already reporting at or near this date, meaning the true temporal sequence of geographic spread occurred before surveillance data capture. The index case dates to 2026-04-24 -- a ~20-day gap before systematic reporting began. Transmission pathway reconstruction is not possible from this data.
