Three fatalities have been linked to a hantavirus outbreak aboard the MV Hondius, which was traveling in the Atlantic Ocean on May 3, 2026. This incident has raised significant concerns about the transmission of this severe disease, primarily associated with rodent exposure.
The World Health Organization (WHO) reported that one case of hantavirus infection has been laboratory confirmed, alongside five additional suspected cases. The first victim, a 70-year-old passenger, developed symptoms while on board and later died.
The unfortunate situation escalated when the victim’s body was transferred to Saint Helena. Tragically, his 69-year-old wife also fell ill and subsequently died in a Johannesburg hospital. Meanwhile, another British passenger, aged 69, remains in intensive care in Johannesburg.
The MV Hondius was operated by Dutch tour company Oceanwide Expeditions and had a capacity of 170 passengers. It was en route from Ushuaia, Argentina, to Cape Verde at the time of the outbreak.
According to the WHO, “Hantavirus infections are typically linked to environmental exposure (exposure to infected rodents’ urine or faeces).” The organization is actively facilitating coordination between national authorities and the ship’s operators to organize medical evacuations for two passengers showing symptoms.
The potential for further cases remains uncertain as officials have not confirmed the nationalities of the victims. Additionally, the exact number of symptomatic passengers aboard is unclear.
This outbreak highlights ongoing concerns regarding hantavirus as it can lead to severe respiratory illness and is primarily transmitted through inhaling airborne particles from rodent urine, droppings, or saliva. As investigations continue, health authorities are working diligently to manage the situation and prevent further infections.
