Americans on cruise with hantavirus outbreak

Big picture view:

About two dozen Americans were on the ship, including about seven who disembarked last month and 17 who remained on board before evacuating this weekend, the Associated Press reported.

It’s not known where the 17 Americans live.

What’s next:

The acting director of the Centers for Disease Control, Dr. Jay Bhattacharya, said Americans would first be flown to the University of Nebraska, which has a federally funded quarantine facility, to assess whether they have been in close contact with any symptomatic people and their risk levels for spreading the virus.

After that, he told CNN’s “State of the Union,” they will be given the choice of staying in Nebraska or going home, where their conditions would be monitored by state and local health agencies.

They’ll be actively monitored for any symptoms that develop within a period of 42 days since the point of last exposure.

Timeline:

Dr. Maria Van Kerkhove, WHO’s Director of Department of Epidemic and Pandemic Management, said Sunday that some strains of the hantavirus can develop symptoms for up to eight weeks after exposure, but the confirmed Andes strain involved in this outbreak develops symptoms within six weeks.

Dig deeper:

Bhattacharya noted the seven Americans who left the cruise earlier have been in the U.S. for roughly two weeks, and they are living across the country.

Meanwhile:

The passengers are leaving behind their luggage, and are allowed to take only a small bag with essential items, a cellphone, a charger, and documentation.

About 30 crew members will stay aboard the ship as it sails back to its origination in Rotterdam, Netherlands, where it will undergo disinfection.
