Things were looking up on Thursday for the more than 2,000 passengers quarantined on a cruise ship in Yokohama, Japan: Meals were coming on a more regular schedule. The internet was upgraded to a wider bandwidth. And there was even official approval to breathe some fresh air.

Still, on the second day of a planned two-week quarantine, there was persistent concern about the spreading coronavirus and dread about long days ahead stuck inside the cabins.

As Japanese health officials concluded the screening of the 273 passengers potentially exposed to the virus, they said that 61 had tested positive. The passengers were removed from the ship and taken to medical facilities.

“I keep hearing painful coughs from a foreigner in a nearby room,” one passenger wrote on Twitter, noting with concern that crew members were delivering meals from room to room. “I might get infected today or tomorrow.”
