A deadly outbreak aboard a Netherlands-operated cruise vessel has claimed three lives and sickened three others, with authorities confirming hantavirus as the suspected cause, according to reports released Sunday.
The virus, which derives its name from South Korea’s Hantan River region where scientists first identified it during the 1970s, is mainly transmitted through rodent contact, though human-to-human transmission can occur in unusual circumstances, the World Health Organization reports.
Infection typically happens when contaminated particles from rat or mouse waste, saliva, and urine become airborne during cleaning activities like sweeping areas where rodents have lived.
This viral family causes two distinct conditions – one targeting lung function and another affecting kidney systems. The respiratory form draws significant medical attention due to its devastating mortality rate of approximately 40 percent.
The lung-affecting variant, known as hantavirus pulmonary syndrome, appears most frequently throughout North and South American regions. Canadian health officials estimate roughly 200 cases of the pulmonary illness emerge globally each year.
A notable recent case involved concert pianist Betsy Arakawa, married to actor Gene Hackman, who succumbed to hantavirus pulmonary syndrome in New Mexico during 2025, autopsy findings confirmed.
Initial symptoms mirror common flu indicators including exhaustion and elevated body temperature, typically appearing one to eight weeks following exposure, Centers for Disease Control officials note.
Within four to ten days, patients develop respiratory distress including persistent coughing, breathing difficulties, and lung fluid accumulation. Medical professionals find early diagnosis challenging within the first three days, as symptoms closely resemble influenza.
No targeted treatment exists for hantavirus infections, leaving doctors to provide supportive measures such as adequate rest and hydration. Severe cases may require mechanical ventilation assistance.
Health experts recommend preventing exposure by controlling and removing rodent populations from human environments. They advise against vacuuming or sweeping dried animal droppings, which can release virus particles into the air.
