The World Health Organization has confirmed an outbreak of hantavirus in Switzerland, following the detection of infections linked to a passenger aboard the MV Hondius cruise vessel.
Health authorities disclosed that the affected passenger responded to a health alert issued by the ship’s operator and subsequently presented himself at a hospital in Zurich, where he is currently receiving medical care.
In line with the International Health Regulations, the WHO said it is collaborating with multiple countries to carry out international contact tracing. The effort is aimed at identifying and monitoring individuals who may have been exposed, in order to prevent further spread of the virus.
Laboratory analysis has confirmed the strain involved as the Andes hantavirus, a rare but potentially severe form of the disease. The confirmation was made through a coordinated effort involving the National Institute for Communicable Diseases in South Africa and Geneva University Hospitals.
Additional technical support has been provided by the Institut Pasteur de Dakar and the Administración Nacional de Laboratorios e Institutos de Salud, reflecting a broad international response to the situation.
As of May 6, health authorities have recorded eight suspected cases linked to the incident, with three already confirmed through laboratory testing. Officials say investigations are ongoing to determine the full scope of the outbreak.
The WHO emphasized that it will continue working closely with affected countries to ensure that patients, passengers, crew members, and their contacts receive the necessary information and support to stay safe.
Authorities have urged vigilance while reassuring the public that measures are being taken to contain the outbreak and minimize the risk of wider transmission.
