Local risk means verified relation to the MV Hondius event.
Country risk is grouped by evidence: confirmed imported case, medical destination, watch or monitoring signal, media-only lead, passenger signal, or low known risk.

A country marker means event relevance. It does not automatically mean local community transmission.
Risk classes used for country interpretation
Confirmed or reported imported case is the strongest country-level signal. It means a positive case is connected to the event through WHO reporting, a national authority, or a reputable report that clearly describes a positive test. Switzerland and the Netherlands are tied to WHO-described case evidence. South Africa appears because Johannesburg was a medical destination in the severe-case chain. France and the United States appear through later reputable reporting of positive evacuated passengers, so they are marked as reported imported cases rather than silently folded into the earlier WHO baseline.
Medical destination is not the same as local spread. Johannesburg matters because event-linked severe illness and death entered the public record there. That marker explains clinical movement and care, not a South African community outbreak. This distinction matters whenever a patient is transferred, evacuated, or treated outside the original exposure location.
Watch, quarantine, isolation, or monitoring means a country has an operational connection to the event. Spain, the United Kingdom, Canada, and Ireland are examples of places where repatriation, isolation, quarantine, or passenger follow-up reporting may matter locally. A watch class points to public-health management, not confirmed infection in the general population.
Media-only or passenger signal is weaker. A country can be relevant because a passenger nationality was reported, because a news article mentioned a return group, or because a local lead needs verification. Japan is included because a Japanese passenger was reported among MV Hondius passengers. That is not the same as a confirmed infection in Japan. Turkey and broader Europe may appear as media signals when reporting is useful for monitoring but not strong enough to change confirmed totals.
Low known risk means no confirmed local infection appears in the current seed dataset. Australia is a good example. It is included because people in Australia and New Zealand may look for a local answer, but the current tracked evidence does not show a confirmed local MV Hondius-linked infection. A low known risk label is not a claim that nothing can ever change; it is a summary of the evidence currently available in this dataset.
How to interpret your country
If a country has a confirmed imported case, the next question is whether local public-health authorities describe broader exposure or contained management. Imported cases can be serious without implying widespread local transmission. The useful details are the source, date, case status, whether the person was part of the ship or repatriation chain, and whether local authorities issued contact instructions.
If a country has monitored passengers, the country is relevant but the people listed are not automatically infected. Monitoring is often precautionary. It can include passengers, close contacts, flight contacts, or groups under isolation while a health authority waits out an incubation window. Monitoring can feel alarming, but it is also how authorities prevent uncertainty from turning into unmanaged risk.
If a country has only a passenger nationality signal, the marker is even narrower. A reported passenger from a country does not equal local disease. Japan illustrates this distinction: a Japanese passenger signal belongs in the dataset because it answers a local relevance question, but it remains far below a confirmed local case.
If a country has no verified relation, the local risk answer remains low known risk for this event. That does not replace general hantavirus prevention guidance. Rodent exposure remains relevant in many places regardless of the MV Hondius story. The country label only describes relation to this event, not every possible hantavirus exposure in daily life.
Risk changes when evidence changes. New public-health bulletins, official imported case confirmations, quarantine updates, contact monitoring notices, laboratory results, corrections, and duplicate removals can all change a rating. Repeated headlines with no new source do not change a rating by themselves.
This information is educational and cannot diagnose infection. People with plausible exposure and concerning symptoms need local medical advice, especially if fever is followed by cough, chest tightness, shortness of breath, dizziness, low oxygen, or rapidly worsening illness.
