May 11 (Reuters) – U.S. Department of Health and Human Services officials said on Monday that 18 passengers from the luxury cruise ship hit by a hantavirus outbreak were flown back to the U.S. and quarantined, with the one passenger who tested positive in a Nebraska biocontainment unit.

The passengers are currently being monitored for hantavirus at U.S. medical facilities, with 16 of them at the University of Nebraska Medical Center (UNMC), and two in Atlanta, including one who is experiencing symptoms, officials from the U.S. Department of Health and Human Services said at a press briefing.

The group had been aboard the MV Hondius, a luxury expedition cruise ship linked to an outbreak of the Andes virus, the only hantavirus species known to be capable of limited spread from person-to-person. Hantavirus is usually spread by wild rodents.

The U.S. health officials said the risk to the general public remains very low. Admiral Brian Christine, assistant secretary for health at the agency, said the Andes virus “does not spread easily” and generally requires prolonged close contact with someone who is symptomatic.

Officials said the two passengers sent to Atlanta were a couple, one of whom had symptoms, and were taken to Emory University’s biocontainment unit to help preserve Nebraska’s capacity for any other passengers who might need higher-level care.

Angela Hewlett, an infectious disease physician and medical director of the Nebraska Biocontainment Unit, said the individual taken there was “doing well” and had not shown any symptoms.

Hewlett said officials would continue monitoring the individual and “ensure that they remain asymptomatic.”

Officials said the quarantined passengers ranged in age from their late 20s to late 70s or early 80s, and could remain under monitoring for up to 42 days.

The group included 17 U.S. citizens and one British dual national who chose to return to the United States.
