Global health authorities are closely monitoring a deadly hantavirus outbreak aboard the Netherlands-registered MV Hondius cruise ship, even as Philippine officials confirmed that all 38 Filipino crew members on board have tested negative for the virus and remain in good condition.
The vessel, operated by Oceanwide Expeditions, has been linked to fatalities among passengers after cases of the Andes virus—a rare but dangerous hantavirus strain—were detected during the voyage.
According to the Department of Migrant Workers, the Filipino crew members will undergo a mandatory 42-day quarantine in the Netherlands before being repatriated to the Philippines. Twenty-four hotel and stewarding personnel are scheduled to disembark in Tenerife, Spain, and fly to the Netherlands, while 14 deck and engine crew members will continue sailing the ship to Rotterdam.
The outbreak has renewed attention on hantaviruses, a group of rodent-borne viruses that can cause severe and sometimes fatal illness in humans. The World Health Organization said people usually become infected through exposure to rodent urine, droppings, or saliva, particularly in enclosed or poorly ventilated spaces.
In the Americas, hantaviruses can trigger hantavirus cardiopulmonary syndrome, or HCPS, a disease that attacks the lungs and heart and can carry fatality rates of up to 50 percent. The Andes virus, commonly found in parts of South America, is the only known hantavirus capable of limited human-to-human transmission through prolonged close contact.
Health experts warn that early symptoms often resemble flu, including fever, headaches, muscle pain, nausea, and fatigue, making early diagnosis difficult. Severe cases can rapidly progress to breathing difficulties and fluid buildup in the lungs.
While no specific cure or vaccine exists, doctors say early medical attention and supportive hospital care significantly improve survival chances.
