Around 6,000 passengers and crew are stuck on a giant cruise ship in an Italian port amid fears that a Chinese tourist on board may have contracted coronavirus.
Specialist doctors are conducting tests on the 54-year-old woman from Macau, who is reportedly suffering from a fever and breathing difficulties.
She has been placed in isolation, along with her husband, in the medical unit of the Costa Smeralda.
The results of tests are expected to be known later today. If the woman is found to be infected, the passengers and crew could face a two-week quarantine aboard the cruise liner.
