The United States is arranging a special evacuation flight to bring home American citizens aboard a cruise ship affected by a hantavirus outbreak. The vessel, MV Hondius, is currently heading toward Spain’s Canary Islands and is expected to arrive in Tenerife on Sunday, according to AFP. A spokesperson for the US State Department said the government is coordinating with Spanish authorities and other federal agencies to ensure the safe repatriation of the passengers.

The ship’s operator reported that 17 US citizens are on board, though the State Department has not confirmed the number. Three people—a Dutch couple and a German woman—have died, and several others have been infected with Andes virus, the only hantavirus known to spread between humans. The Centers for Disease Control and Prevention (CDC) stated that the repatriated passengers will first be taken to Offutt Air Force Base in Omaha, Nebraska, before being transferred to the National Quarantine Unit at the University of Nebraska Medical Center.

CDC and Nebraska Medicine said the risk to the US public remains very low, and those under observation are currently healthy and symptom-free.
