Health authorities are investigating a suspected hantavirus outbreak aboard the cruise vessel MV Hondius after three passengers died during the voyage from Argentina to Cape Verde.

According to the World Health Organization, one case has been confirmed so far, while five others remain under investigation. Laboratory testing is underway to identify any additional infections and determine the source of the outbreak.

The incident has drawn attention because hantavirus infections are usually linked to rodents and human-to-human transmission is considered rare.

Hantavirus is a group of viruses commonly carried by rodents. People are typically infected by breathing in contaminated particles from dried urine, droppings or saliva of infected animals. In some cases, infection can also occur through rodent bites or scratches.

The virus can cause two serious illnesses. One is Hantavirus Pulmonary Syndrome, which starts with flu-like symptoms such as fever, fatigue and muscle pain before progressing to severe breathing problems. Once respiratory symptoms develop, the disease can become life-threatening.

The other is Hemorrhagic Fever with Renal Syndrome, which mainly affects the kidneys and can lead to low blood pressure, internal bleeding and kidney failure in severe cases.

There is currently no specific antiviral treatment for hantavirus. Patients are usually given supportive care, including oxygen, ventilation or dialysis depending on the severity of the illness.

Although infections remain uncommon, the outbreak on board MV Hondius has renewed concern about the risks of infectious disease in enclosed settings and the need for early detection and strict hygiene measures.

Health experts say prevention remains the best defense, including avoiding contact with rodents, sealing entry points and using protective gear when cleaning potentially contaminated areas.
