A shocking health scare emerged at sea in May 2026 after a rare Hantavirus outbreak was linked to multiple deaths on a cruise ship. The disease made headlines last year when he died Gene Hackman and his wife, Betsy ArakawaHe died as a result of the virus.
Here’s everything to know about the disease, whether it can be treated and what exactly happened on the cruise ship in May 2026.
What is Hanta virus?
Hantavirus is a rare, potentially life-threatening virus that spreads primarily through contact with the urine, droppings or saliva of infected rodents, according to the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). In humans, it can cause serious conditions, including Hantavirus pulmonary syndrome, which often begins with flu-like symptoms before developing into severe respiratory problems.
Although cases of hantavirus are uncommon, the disease can quickly become severe.
The World Health Organization is aware of and supports a public health event involving a cruise ship sailing in the Atlantic Ocean. To date, one case of Hantavirus infection has been laboratory confirmed, and five additional cases are suspected. Of the six affected individuals, three died… pic.twitter.com/SqMAAZzoID

Can Hanta virus spread from person to person?
Health experts note that human-to-human transmission of Hantavirus is extremely rare, and that most infections result from environmental exposure to rodents and their bodily fluids.
However, one type of hantavirus, the Andean virus, is known to be able to transmit from person to person, but it is rare. This type of virus is mainly found in Chile and Argentina, where cruise ships originate.
Can Hanta virus be treated?
There is currently no specific treatment or antiviral treatment for Hantavirus. Medical care usually focuses on supportive treatment, such as oxygen therapy or intensive care for severe cases.
Early detection of the virus is crucial. Patients who receive immediate medical care — especially before severe respiratory symptoms appear — tend to recover in time. However, the virus can be fatal in some cases, with certain strains carrying high mortality rates.
Which cruise ship was hit by a Hantavirus outbreak in 2026?
The outbreak occurred on board the MV Hondius, a polar exploration ship operated by Oceanwide Expeditions. The ship was traveling across the Atlantic Ocean from Argentina towards Cape Verde when passengers began feeling ill, and reports emerged on May 3.
Health authorities, including the World Health Organization, launched an investigation while coordinating medical evacuations and tests to determine the source of infection.
How many deaths have occurred during a cruise with Hantavirus?
At least three people have died during the outbreak, and several additional suspected or confirmed cases have been reported among passengers.
