EA-01: Four Hong Kong Schools, Huangshan
Mass Illness · East Asia · Hong Kong → China · 2025
What Happened
In February 2025, students and teachers from four Hong Kong secondary schools on a 5-day exchange to Huangshan, China reported gastroenteritis symptoms. Of 43 participants, 11 students and 2 teachers fell ill. One student reported the first evening's meal had a "sour taste" initially dismissed as local cuisine. The outbreak spread via person-to-person transmission on the tour bus.
Outcome
11 students and 2 teachers ill; 10 sought medical attention; 9 tested positive for norovirus; Education Bureau suspended the restaurant and prohibited raw food in future exchange programmes
Quality Gaps Identified
- The tour organiser failed to vet the restaurant's food hygiene standard before the trip
- Students noticed the food tasted off — no pre-trip inspection process was in place
- No protocol for managing infectious illness on a group transport vehicle
