Four states scramble to track cruise passengers after a hantavirus outbreak left three dead and WHO said one strain spreads like the flu
Precaution is key.
Four states are racing to track cruise passengers after a hantavirus outbreak on a ship left three people dead and the World Health Organization confirmed one strain spreads like the flu. The MV Hondius, a Netherlands-based cruise ship, became the center of a public health alert after eight passengers tested positive for the virus. Health officials in Georgia, California, Arizona, and Virginia are monitoring residents who were on board, though most are currently symptom-free.
According to The Hill, the ship, which carried nearly 150 people, had sailed from Argentina toward Antarctica before crossing the Atlantic. It remains docked off the coast of Cape Verde, an island near Africa. According to reports, between 29 and 40 passengers disembarked at St. Helena, a remote island in the South Atlantic. The outbreak has raised concerns because the confirmed Andes virus strain can spread from person to person, a rare but dangerous trait for hantaviruses.
WHO held a news briefing on May 7, 2026, to address the situation. Director-General Tedros Adhanom Ghebreyesus confirmed that five of the eight cases were lab-confirmed as hantavirus, while the other three remain suspected. He also noted that three passengers with suspected cases were evacuated from the expedition and cruise ship earlier this week.
Despite the severity of the outbreak, public health risk remains low
The Centers for Disease Control and Prevention (CDC) echoed this assessment by WHO, though health departments across the U.S. aren’t taking any chances. Georgia’s Department of Health is monitoring two residents who were on the cruise. Both are reportedly in good health and show no signs of infection.
California’s Department of Public Health is assisting local authorities in tracking an unspecified number of passengers, while Arizona is keeping tabs on one resident who isn’t showing symptoms. Virginia’s Department of Health confirmed it’s monitoring one traveler, who is also asymptomatic. The cautious approach makes sense since hantavirus can be deadly, and early symptoms are easy to mistake for something less serious.
Hantavirus isn’t new, but it’s not something most people think about unless they’ve been in close contact with rodents. The virus is typically spread through urine, saliva, or droppings from infected rodents, especially when the particles become airborne and are inhaled. The Andes virus, however, breaks the mold.
Unlike most hantaviruses, which don’t spread between humans, the Andes strain can jump from person to person under certain conditions. That’s why health officials are treating this outbreak with extra urgency, even if the overall risk is low. Symptoms usually start showing up between one and eight weeks after exposure. Early signs are flu-like – fever, chills, muscle aches, and headaches.
If the disease progresses, it can lead to chest tightness as the lungs fill with fluid. In some cases, hantaviruses can also cause hemorrhagic fever and kidney damage, which typically appears one to two weeks after the first symptoms. There’s no specific treatment or cure, which is why prevention and early detection are so critical.
This is a stark reminder of how quickly infectious diseases can spread in confined spaces
The MV Hondius had passengers from multiple countries, including 17 Americans, which is why health departments in four states are now involved. The ship’s route, from Argentina to Antarctica and then across the Atlantic, meant passengers were exposed to different environments, some of which may have had higher rodent activity. While the exact source of the outbreak hasn’t been confirmed, the timing and symptoms align with hantavirus exposure.
For now, the focus is on monitoring those who were on the ship. Most of the passengers under observation are asymptomatic, but health officials aren’t taking any risks. The fact that three people have already died underscores how serious this virus can be. The WHO and CDC are keeping a close eye on the situation, but they’ve stopped short of issuing broader travel warnings.
Hantavirus isn’t something most people worry about on a daily basis, but outbreaks like this one show why public health surveillance is so important. The fact that four states are actively monitoring passengers speaks to how seriously officials are taking the threat. Even if the risk is low, the potential consequences are severe enough to warrant extra caution. For now, the best advice is to stay informed, watch for symptoms, and follow any guidance from health authorities.
