A first group of passengers, all Spanish nationals and none displaying symptoms of infection, disembarked from the ship into small boats as the vessel approached the Port of Granadilla in Tenerife, Spain’s health ministry said.

Spanish officials said the passengers would be transported in sealed military buses directly to Tenerife’s airport before being flown aboard a government aircraft to Madrid for hospital evaluation and quarantine measures.

Authorities said all passengers would undergo testing by Spanish health officials before onward transport. Foreign nationals are expected to be repatriated in stages using specially arranged flights coordinated by their respective governments rather than commercial air services.

The European Centre for Disease Prevention and Control, or ECDC, classified all passengers and crew as high-risk contacts as a precautionary measure in rapid scientific guidance issued late Saturday. The agency said symptomatic passengers should receive priority medical evaluation and testing upon arrival and may either remain isolated in Tenerife or be medically evacuated home depending on their condition.

Thirty crew members are expected to remain aboard the vessel, which will later sail to the Netherlands for disinfection operations, according to Spanish authorities.The ship departed waters off Cape Verde earlier this week after the World Health Organization and the European Union requested Spain coordinate the evacuation effort following confirmation of the outbreak.

WHO Director-General Tedros Adhanom Ghebreyesus arrived in Tenerife on Saturday alongside senior Spanish ministers to oversee preparations for the ship’s arrival and passenger transfer operations.The WHO said eight people aboard the vessel had fallen ill, including three fatalities involving a Dutch couple and a German national.

Six infections have been laboratory confirmed, while two additional cases remain under investigation.Hantavirus is primarily transmitted through exposure to infected rodents, though health officials say limited person-to-person transmission can occur in rare circumstances.

The WHO has assessed the risk to the wider global population as low while describing the threat to passengers and crew aboard the vessel as moderate.Spanish authorities said evacuation operations were expected to continue throughout the day under strict biosecurity protocols at Tenerife’s Port of Granadilla.
