Theater: European cruise departure/arrival ports
Time horizon: 24h

Moderate confidence (70%)
Risk direction: volatile · Impact: MEDIUM
Executive summary
Within 24 hours, the emerging hantavirus maritime cluster linked to an Antarctic cruise is likely to trigger immediate tightening of health screening and sanitation protocols in the cruise industry and selected connecting airports. Port health authorities in Europe and the Americas will increase surveillance of passengers and crew associated with affected itineraries, potentially including short-term quarantine or testing measures. Airlines serving key hub routes to/from impacted ports may face new screening requirements. While public panic will be limited, sector-specific disruptions and localized anxiety are probable.
