Hantavirus Outbreak on Cruise Ship: CDC Assures Extremely Low Risk to Public

WASHINGTON: (Web Desk) – The Centers for Disease Control and Prevention has stated that the risk to the general public from a hantavirus outbreak aboard a cruise ship remains “extremely low,” as evacuation efforts are being prepared for passengers and crew.

The statement comes after multiple confirmed and suspected cases of hantavirus were reported on the expedition vessel M/V Hondius, which had been travelling from South America across the Atlantic with around 150 people on board.

According to health authorities, three individuals have died due to the rare but potentially deadly virus, while several others have tested positive or are under observation. Evacuation of remaining passengers is expected to begin on May 11 via Tenerife in Spain.

The World Health Organization (WHO) confirmed that the first fatal case likely contracted the virus before boarding the ship, as the incubation period of hantavirus ranges from one to six weeks. Experts say infection is typically linked to exposure to infected rodents.

A WHO official also clarified that human-to-human transmission is extremely rare and only documented in specific strains under close contact conditions.

The vessel is currently anchored near Cape Verde and is expected to proceed toward the Canary Islands as coordination continues between international health authorities and maritime officials for safe evacuation and treatment procedures.

Health officials have stressed that there is no indication of widespread transmission risk beyond those directly exposed onboard the ship.
