Moderate confidence (70%)
Risk direction: volatile · Impact: MEDIUM
Executive summary
Over the next week, WHO and national health agencies are likely to issue updated technical guidance, case definitions, and surveillance recommendations related to the hantavirus maritime cluster, aiming to harmonize responses across ports and airlines. Countries may implement targeted screening of passengers and crew linked to the affected cruise and possibly similar itineraries, but broad travel bans or quarantines for entire nationalities or regions are unlikely. Health systems in some port cities will conduct tabletop exercises or small drills to test readiness. Public concern will persist but be moderated by official messaging that the outbreak remains limited and controllable.
