Earlier we told you about the outbreak on the MS Roald Amundsen, a Norwegian cruise ship where at least 41 passengers and crew have tested positive for Covid-19.

This is the latest blow to an industry that has been hit hard by the pandemic, with shares in the major global operators falling dramatically since the start of March.

While the industry has restarted in recent times, there have already been setbacks.

A crew member on a ship in the Pacific tested positive for the virus on Sunday. The Paul Gauguin was forced to suspend its journey when the case was detected by the ship's doctor, local media report.

Passengers were then told to stay in their cabins as the ship turned back to Papeete on the island of Tahiti, where all on board are being tested.

Ahead of resuming its operations, Ponant, the company that runs the Paul Gauguin, had reassured customers in a blog post that it had strict regulations in place that "go further than the international standards for the sector".

But cruise companies are expecting strong bookings for 2021. They are reporting a combination of new bookings and people using vouchers they received for cancelled cruises this year.

"We absolutely believe when we come out of this we will lean into our repeat cruisers," Christine Duffy, the president of Carnival Cruise line, told Reuters news agency. "They really are the ambassadors for the cruise industry."
