The World Health Organization (WHO) has confirmed an additional case of hantavirus linked to an outbreak on the MV Hondius cruise ship, after a passenger sought treatment in Zurich.
Swiss health authorities identified the case when the individual responded to a health alert issued by the ship’s operator and subsequently presented at a hospital in Zurich, according to the WHO. The agency is now coordinating with countries under the International Health Regulations (IHR) to trace contacts and prevent further transmission.
In a statement posted on X, the WHO said: “Swiss authorities have confirmed a case of #hantavirus identified in a passenger from the MV Hondius cruise ship.”
The organisation added: “In line with the IHR, WHO is working with relevant countries to support international contact tracing, to ensure that those potentially exposed are monitored and that any further disease spread is limited.”
Laboratory testing has confirmed that the outbreak involves the Andes strain of hantavirus. The strain was identified by health laboratories in South Africa and Switzerland, with additional support from laboratories in Senegal and Argentina.
As of 6 May, the WHO reported eight cases linked to the outbreak, three of which have been confirmed by laboratory testing. Earlier cases on the Dutch-flagged vessel included fatalities and medical evacuations, prompting an expanded international response as authorities continue to monitor passengers and crew.
The WHO has pledged to continue working with affected countries to ensure that patients, contacts, passengers and crew receive the necessary support and information to remain safe.
