Two Houston Residents Monitored After Deadly Cruise Ship Hantavirus Outbreak

Outbreak Forces International Response

Two Houston residents are among passengers being monitored after traveling aboard the MV Hondius, a luxury cruise ship now at the center of a deadly hantavirus outbreak in the Atlantic Ocean. The two Texas residents who were passengers on the MV Hondius ship that has been at the center of a hantavirus outbreak have been confirmed as residents in the City of Houston , according to city officials.

As of Wednesday, the World Health Organization reported eight total cases, five of which have been laboratory-confirmed as the Andes strain of hantavirus. Three people have died . The outbreak has prompted an unprecedented international response, with at least 12 countries currently monitoring people who had disembarked the MV Hondius before cases of hantavirus were confirmed .

The passengers left the ship and returned to the United States before the outbreak was identified. Public health workers in Texas have reached the two individuals, and they report they are not experiencing any symptoms and did not have any contact with a sick person while aboard the ship .

Rare Human-to-Human Transmission Suspected

What makes this outbreak particularly concerning is the virus strain involved. While most hantaviruses are spread through contact with infected rodent droppings or urine, the Andes strain is unique for its ability to spread between humans . The strain in the Hondius outbreak, Andes virus, can spread from person to person in limited circumstances. It typically requires close, prolonged contact with a person who is actively sick with the disease .

Investigators are focusing on the theory that the outbreak began during a land excursion before the ship set sail. Argentine officials told The Associated Press that a Dutch couple may have contracted the virus during a bird-watching tour in Ushuaia, Argentina. The couple reportedly visited a landfill during the tour, where they may have been exposed to infected rodents .

The timeline of deaths aboard the ship supports human transmission theories. On 6 April, a 70-year-old Dutchman began showing symptoms. He then became the first to die on board the ship on 11 April . His widow boarded a flight from Johannesburg to Amsterdam, but was removed from the plane before takeoff due to her medical condition, and she died in a hospital in South Africa on the same day .

Extensive Monitoring Protocols

The passengers have agreed to daily temperature checks and self-monitoring. They are instructed to contact health officials immediately if any signs of illness appear, as symptoms can take up to eight weeks to manifest after exposure . Officials have put into place safety protocols for first responders, specifically for any service calls involving the passengers who are monitoring themselves of symptoms .

Five U.S. states have said they are monitoring passengers who debarked the Hondius prior to any cases being confirmed on board for signs of the rare and often deadly disease: two each from Georgia and Texas, one from Virginia, one from Arizona, and an unspecified number from California, according to their respective state health departments. Each state has said none of the individuals is exhibiting any signs of the illness .

At this time, the risk to the American public remains extremely low , according to the CDC. The U.S. government's top priority is the safe repatriation of American passengers. These individuals are planned to be evacuated on a U.S. government medical repatriation flight to Offutt Air Force Base in Omaha, Nebraska, where they will be transported to the National Quarantine Center at the University of Nebraska, Omaha .

Ship Remains Stranded

The MV Hondius remains in international waters as officials debate where it can safely dock. The Dutch cruise ship is now on its way to Tenerife, in the Canary Islands, where it is expected to arrive on Sunday, 10 May . However, the president of the Canary Islands, Fernando Clavijo, said he "cannot allow [Hondius] to enter the Canaries" and refused to receive the ship in Tenerife .

This outbreak represents a convergence of rare circumstances - a luxury polar expedition, an unusual virus strain capable of human transmission, and the logistical nightmare of managing an infectious disease outbreak on the high seas. As monitoring continues across multiple continents, health officials face the challenge of tracking potential cases while balancing public safety with humanitarian obligations to those still aboard the vessel.
