Location: The MV Hondius is currently anchored off Praia, Cape Verde, after traveling from Argentina towards the Canary Islands.
Impact: Three passengers have died, and others have shown symptoms of severe respiratory illness. One British passenger was evacuated to South Africa, where they tested positive for a hantavirus variant.
Cases: As of the latest reports, one case was laboratory-confirmed, with five other suspected cases (including two crew members).
Response: Passengers were instructed to remain in cabins while the vessel underwent sanitization, according to reports.
Transmission: Hantaviruses are typically transmitted to humans through contact with rodent droppings or urine, particularly when the material becomes airborne. While human-to-human transmission is rare, it has been mentioned as a potential factor in this scenario.
Symptoms: Initial symptoms are flu-like—fever, chills, body aches, and headaches—which can progress rapidly to serious respiratory failure.
Risk: The World Health Organization (WHO) stated that the risk to the general public remains low.
Severity: Hantavirus pulmonary syndrome is highly fatal, with studies indicating a roughly 40% death rate.
