US health officials have issued quarantine orders for two passengers from the cruise ship at the centre of a hantavirus outbreak who are now at a hospital in Nebraska.
The orders were signed by the Centers for Disease Control and Prevention's acting director, Jay Bhattacharya, the CDC said in a statement on Tuesday.
Quarantine orders, which can be enforced with fines and prison time, are a rare legal step that can be taken if someone objects to a public health request.
