WHO Reassures Public Over Hantavirus Cases Linked to Cruise Ship Outbreak

The World Health Organization has moved to calm growing public concern over recent hantavirus infections linked to a cruise ship outbreak, stressing that the situation is not developing into an epidemic or pandemic.

Health officials confirmed that eight hantavirus cases have been identified so far, including five laboratory-confirmed infections. Three people — a Dutch couple and a German national — have died following the outbreak connected to the MV Hondius expedition cruise.

Speaking at a press conference in Geneva, WHO officials emphasized that the virus behaves very differently from COVID-19 and currently presents a low public health risk.

Maria Van Kerkhove, WHO Director for Epidemic and Pandemic Management, stated that hantavirus is far less contagious than coronavirus and insisted that the current situation should not be compared to the global pandemic experienced in 2020.

WHO Director-General Tedros Adhanom Ghebreyesus also confirmed that health authorities are closely monitoring people who had contact with infected individuals and are showing symptoms.

Experts believe the outbreak may remain limited if countries continue applying strict public health measures and maintain international cooperation.

Hantavirus is typically transmitted through infected rodents and their excretions. However, certain variants, including the Andes virus, can occasionally spread through close human contact in rare situations.

WHO officials warned that additional infections could still emerge because the incubation period can last up to six weeks.

Authorities in several countries are continuing retrospective contact tracing efforts to identify and monitor individuals who may have been exposed during the cruise.

In Switzerland, contact tracing measures were launched after an infected patient was admitted to Zurich University Hospital.

Despite international attention surrounding the outbreak, WHO continues to classify the overall risk to the general public as low.

Health experts are encouraging people to remain informed while avoiding unnecessary panic, noting that hantavirus outbreaks remain rare and typically limited in scale.
