According to ECDC (assessment of 6 May 2026), the risk to the general population in Europe remains "very low." Widespread transmission is not expected, because close and prolonged contact is required for transmission and infection-prevention measures are in place onboard and at disembarkation. Significant uncertainties remain; investigations are ongoing.
