Hantavirus Outbreak on MV Hondius Cruise Ship Results in Three Deaths

A suspected hantavirus outbreak aboard the MV Hondius cruise ship has resulted in three deaths and several illnesses among passengers and crew. The vessel, currently anchored off the coast of Cape Verde, had departed from Ushuaia, Argentina, in March with approximately 150 individuals on board.

The World Health Organization (WHO) has identified seven cases of the acute respiratory virus, including three fatalities. The deceased include a Dutch couple and a German man. A British passenger, who was evacuated to South Africa, remains in critical condition.

Hantaviruses are typically transmitted to humans through contact with contaminated rodent excreta. However, the WHO is investigating potential human-to-human transmission in this instance. Maria Van Kerkhove, the WHO's director of epidemic and pandemic preparedness and prevention, stated, "We do believe that there may be some human-to-human transmission that's happening among the really close contacts, the husband and wife, people who've shared cabins."

The ship's operator, Oceanwide Expeditions, reported that two crew members—one British and one Dutch—are exhibiting acute respiratory symptoms, with one case being severe. Cape Verdean authorities have denied the ship permission to dock due to health concerns, and medical evacuations are being coordinated for the critically ill individuals.

Investigations are ongoing to determine the outbreak's origin. The WHO suggests that initial infections may have occurred during excursions in Argentina, where the Andes virus strain of hantavirus is prevalent. This strain is known for its potential human-to-human transmission.

Passengers and crew are currently confined to their cabins as a precautionary measure. The WHO is collaborating with international health agencies to manage the situation and prevent further spread of the virus.
