An American passenger trapped on the coronavirus-stricken Diamond Princess cruise ship docked in Japan says mandatory quarantine is like “being trapped in your bathroom,” according to a report.

Californian Matthew Smith, 57, has been stuck in his cabin with his wife, Katherine, for nearly a week since passengers were put on lockdown to prevent the spread of the coronavirus, CNBC reported.

“Imagine being trapped in your bathroom and that would give you a kind of idea of that,” Smith told CNBC’s “Squawk Box.”

Princess Cruise has confirmed there have been 136 cases of the coronavirus among the ship’s passengers and crew members — including 24 Americans.

Though he’s mostly relegated to his cabin, Smith said that passengers have been allowed to leave their rooms in “small groups to get some air, which is obviously necessary.”

“We have been more comfortable than most on board,” he said

Smith said the crew drops off meals three times a day at their door — in addition to other visits to bring medication and bottled water.

“We have menu choices for lunch and dinner. They’ve been providing us with sodas and called up and got some sparkling water for my wife tonight,” Smith told the outlet.

He has been posting quippy reviews of the meals on social media.

He told CNBC that it “can be a little depressing” in the room, but he maintains hope that they’ll be able to disembark at the end of the 14-day quarantine period.

“I give Princess and the captain of this vessel an A plus-plus on their response on this,” he said. “They faced a situation that I expect they had no plans for.”
