Health authorities across a dozen countries are now tracking passengers who disembarked from the MV Hondius cruise ship, following a confirmed outbreak of a potentially fatal hantavirus strain. The virus has led to at least three deaths and several suspected infections among those who were on board the vessel.
The World Health Organization (WHO) confirmed on Thursday that international efforts are underway to monitor individuals who left the ship before the severity of the outbreak became apparent. In the United States, health agencies in Georgia, Arizona, and California are actively monitoring residents who were passengers. Specifically, two residents in Georgia are under observation, with public health officials stating they are currently in good health and adhering to CDC recommendations.
The MV Hondius, which began its voyage from Argentina on April 1, had nearly 150 people on board. Cases have now spread beyond the ship itself. A flight attendant in South Africa was hospitalized with suspected symptoms after potentially coming into contact with a sickened passenger. Separately, a Swiss passenger who returned home tested positive for the virus and is receiving treatment. The WHO emphasized that this situation does not indicate the start of a pandemic.

The ship is currently en route to the Canary Islands. Remaining passengers aboard the MV Hondius are reportedly being asked to remain in their cabins while awaiting disembarkation, contingent on them showing no symptoms. A WHO expert and Dutch infectious disease physicians are currently on board the vessel.
The first confirmed case of hantavirus in a passenger on the ship was identified on May 2, according to the WHO. One of the earliest confirmed deaths was a Dutch man who died aboard the ship on April 11. Close contacts of those affected are also reportedly self-isolating. Lab tests have confirmed the specific strain responsible for the outbreak on the MV Hondius. The exact source of the virus's introduction to the ship remains under investigation.
