At least three cruise lines have cancelled trips to China, while one passenger ship is being isolated at an Italian port as a precaution against the Coronavirus outbreak.

Voyages from Shanghai cancelled

Royal Caribbean has sidelined two voyages from Shanghai, while Italy's Costa Cruises has scuttled four ships from travelling to China after four passengers reported having a fever while onboard one vessel that left Shenzhen, China on Monday. A third line, MSC Cruises reported cancelling one trip departing from China.

Other cruise lines like Norwegian, Regent Seven Seas and Silver Sea have not confirmed any cancellations. But all reported adopting heavy screening and non-touch temperature tests to their boarding protocol to check out passengers who had been in Wuhan in the last month. Passengers recording a body temperature of at least 100.4 degrees Fahrenheit will not be allowed onto any of those ships.

Port confines 7,000 passengers

Meanwhile, the Carnival Cruise Line-owned Costa has one of its ships, the Costa Smeralda, being held at the port of Civitavecchia in Italy, after one 54-year-old woman reported fever symptoms. Roughly 7,000 people remain confined to the vessel until further notice. So far, medical reports have not found any evidence of the virus in the woman who is still in isolation.

The virus, which was first discovered earlier in January in Wuhan, China has to date killed more than 130 people and infected nearly 6,000. Other countries reporting infections include the U.S., Canada, Germany and Taiwan.
