A suspected outbreak of hantavirus on the MV Hondius, a cruise ship sailing in the Atlantic Ocean near Cape Verde, has killed three people and sickened at least three others as of May 3, 2026. This incident marks the first known outbreak associated with cruise ships, raising significant public health safety concerns.
Key facts:
- Three individuals have died, including an elderly couple from the Netherlands.
- At least three others have been reported sick, with one confirmed case of hantavirus infection.
- Around 150 passengers were onboard at the time of the outbreak.
- The ship had left Argentina three weeks prior to the outbreak.
The World Health Organization is aware of and supporting a public health event involving the MV Hondius. Local authorities have not allowed anyone to disembark while investigations continue. One patient remains in intensive care in a South African hospital, while two crew members require urgent medical assistance.
Hantaviruses are primarily spread through contact with infected rodent urine or feces. Nicole M. Iovine, MD, PhD, noted that it is possible isolated cases may have occurred previously without recognition as hantavirus infections. The strain involved in this outbreak remains unknown.
This situation underscores the importance of effective cruise ship sanitation and rigorous public health risk assessment protocols to prevent similar outbreaks in the future.
