Global health authorities are scrambling to contain a hantavirus outbreak linked to the MV Hondius cruise ship after multiple infections and deaths were reported among passengers.
The U.S. Centers for Disease Control and Prevention (CDC) has classified the incident as a “Level 3” emergency response, the lowest tier of emergency activation, indicating that the risk to the general public remains low while health officials continue to monitor developments closely.
According to U.S. News, the outbreak involves the Andes strain of hantavirus and has so far resulted in five confirmed cases, three suspected infections, and three deaths connected to the voyage.
The MV Hondius, which carried about 150 passengers and crew members from 23 countries, reportedly departed Argentina before crossing the Atlantic Ocean. Health concerns emerged after several passengers developed respiratory-related symptoms while the vessel was sailing near Cape Verde.
In response to the outbreak, the CDC activated its Emergency Operations Center to coordinate monitoring and support response efforts.
“The activation of the emergency team is part of routine public health preparedness and does not indicate a high risk to the wider public,” health officials said.
The World Health Organization (WHO) is also reportedly collaborating with international health agencies to trace contacts and contain the spread of the virus.
Hantaviruses are primarily transmitted through contact with infected rodents, especially rats and mice. Humans can become infected after inhaling airborne particles from rodent urine, saliva, or droppings, often during cleaning activities in contaminated areas.
Medical experts say the virus can initially present with flu-like symptoms such as fever, fatigue, and muscle aches before progressing to severe respiratory illness or kidney complications.
“Hantavirus infections can deteriorate rapidly once respiratory symptoms develop,” a public health expert familiar with the outbreak said. “Early detection and supportive treatment are critical to improving survival chances.”
Health authorities noted that some hantavirus strains can carry mortality rates of up to 50 percent, depending on the severity of infection and speed of medical intervention.
Officials are continuing investigations to determine how exposure occurred aboard the cruise ship and whether additional passengers may have been infected.
