A global search is underway to trace passengers who left the MV Hondius after a deadly hantavirus outbreak struck the luxury cruise ship travelling from Ushuaia, Argentina, to Cape Verde, Africa. The virus, carried by rats, has already claimed three lives and infected several others, prompting an urgent international response to stop further spread and protect the more than 20 British nationals onboard who face possible quarantine for up to eight weeks.
How Hantavirus Spreads
Hantavirus is primarily found in rodents and transmits to humans through contact with urine, faeces, or saliva, which can become airborne. Human infection can also occur via bites, scratches, or handling contaminated food. The outbreak strain is believed to originate from the long-tailed pygmy rice rat, common in the affected region.
Recognising Symptoms
Symptoms typically appear two to four weeks after exposure and often resemble flu – including fever, aches, nausea, and vomiting. Some cases remain mild or asymptomatic, making the virus hard to detect early. Serious infections may develop into hantavirus pulmonary syndrome (HPS), leading to respiratory failure, or haemorrhagic fever with renal syndrome (HFRS), which causes kidney failure and internal bleeding.
Limited Human-to-human Transmission
Experts stress hantavirus is not easily passed between people. Infection usually requires close, prolonged contact such as living in the same room. Casual contact, including passing someone in communal areas or dining queues, poses a very low risk.
Global Response And Safety Measures
Passenger repatriation efforts are ongoing, while the World Health Organisation has reassured the public that this outbreak is not comparable to the Covid pandemic. Strict isolation measures, hygiene protocols, and medical monitoring remain in place for those still onboard. Travel experts advise against cancelling holidays solely due to the virus, urging vigilance instead.
Treatment And Risks
There is no licensed antiviral treatment yet, but supportive care including oxygen therapy is available. Antiviral medications like ribavirin are used compassionately, though evidence of efficacy is limited. Older individuals and those with underlying health issues face higher risk of severe disease.
