World Health Organization Director-General Tedros Adhanom Ghebreyesus today briefed the media on a cluster of hantavirus cases linked to the cruise ship MV Hondius.
So far, health authorities have reported eight cases associated with the incident, including three deaths. Among these, five cases have received laboratory confirmation for hantavirus infection.
Andes Virus Identified in Confirmed Cases
According to WHO, the infections involve the Andes virus, the only hantavirus species known to cause limited human-to-human transmission. However, such transmission generally occurs through close and prolonged contact.
While addressing the situation, Dr Tedros stated, “While this is a serious incident, WHO assesses the public health risk as low.”
At the same time, he cautioned that additional cases may emerge because of the virus’s incubation period.
WHO Coordinates International Response
WHO is currently coordinating closely with multiple countries under the framework of the International Health Regulations (IHR). These regulations define the responsibilities and obligations of countries and WHO in responding to international public health events.
Dr Tedros noted that the incident highlights the importance of global cooperation and solidarity in managing health threats that cross national borders.
WHO Prioritises Patient Care and Passenger Safety
“Our priorities are to ensure the affected patients receive care, that the remaining passengers on the ship are kept safe and treated with dignity, and to prevent any further spread of the virus,” Dr Tedros said.
In response to the outbreak, WHO has initiated several measures since receiving notification of the situation on Saturday, 2 May 2026.
Expert Deployed Onboard for Risk Assessment
As part of its response efforts, WHO has deployed an expert onboard the ship to support a comprehensive medical assessment of all passengers and crew members.
Additionally, the expert team is gathering critical information to evaluate the infection risk among those onboard and guide further public health measures.
WHO Strengthens Testing Capacity Across Countries
To improve diagnostic preparedness, WHO has arranged the shipment of 2,500 diagnostic kits from Argentina to laboratories in five countries.
This step aims to strengthen testing capacity and support faster detection of potential cases.
Operational Guidance Being Prepared
Furthermore, WHO is developing detailed operational guidance to support the safe and respectful disembarkation and onward travel of passengers and crew once the ship arrives.
The guidance will help countries manage the situation effectively while protecting public health and ensuring the dignity and safety of those affected.
