Swiss Crew Member Identified on Hantavirus-Hit Cruise Ship

A Swiss national has been identified among the crew members aboard the MV Hondius, which recently experienced a hantavirus outbreak during an expedition voyage.

According to Anne Lévy, the Swiss crew member had contact with infected individuals but is currently not showing any symptoms.

Speaking to Swiss public broadcaster SRF, Lévy confirmed that the man remains onboard the ship and is being monitored as a precautionary contact case.

The outbreak aboard the Hondius has already resulted in multiple confirmed hantavirus infections and several deaths, attracting international health attention.

The World Health Organization has now taken responsibility for coordinating the public health response connected to the ship.

Officials stated that once the vessel arrives in Tenerife, WHO experts will decide on further medical procedures and patient management.

Cruise operator Oceanwide Expeditions said that no passengers or crew members are currently displaying symptoms onboard the ship.

According to the company, the MV Hondius is expected to arrive at the port of Granadilla in Tenerife on Sunday morning.

Swiss authorities continue to monitor the situation closely while maintaining that the public health risk in Switzerland remains low.

Health experts say hantavirus infections are rare and are usually linked to contact with infected rodents, although limited human-to-human transmission has been reported in certain virus variants.

International health agencies are continuing contact tracing and precautionary monitoring efforts following the outbreak.

Hantavirus Case Treated at Zurich University Hospital.

A man infected with hantavirus is currently receiving treatment at the Zurich University Hospital, according to the Swiss government. Authorities emphasized that there is no danger to the general population.

The patient was previously a passenger aboard the cruise ship MV Hondius, where several hantavirus cases were reported during a voyage in the Atlantic Ocean.

According to the Federal Office of Public Health, the man returned to Switzerland at the end of April after traveling in South America with his wife. He later developed symptoms and was immediately isolated upon arrival at Zurich University Hospital.

Laboratory testing conducted at the reference facility at Geneva University Hospital confirmed infection with the virus. His wife has not shown symptoms but has entered precautionary self-isolation.

Health authorities are currently investigating whether the patient had contact with other individuals after returning to Switzerland.

Officials stated that the risk to the Swiss population remains low. The European variant of hantavirus is typically transmitted through contact with infected rodents, while human-to-human transmission is extremely rare and mainly associated with the Andes virus strain.

The FOPH noted that hantavirus infections are uncommon in Switzerland, with only zero to six cases reported annually in recent years, most of which are linked to infections acquired abroad.

Meanwhile, the MV Hondius cruise ship, operated as part of luxury expedition voyages, has been linked to a wider outbreak affecting nearly 150 passengers and crew from multiple countries. Several deaths have been reported, and some patients are receiving intensive care treatment internationally.

The outbreak developed during a long expedition route from South America toward Antarctica and across the South Atlantic, raising concerns among global health authorities, including the World Health Organization, which continues to assess the situation.
