TOKYO (Reuters) - Dozens more people on a cruise ship quarantined in a Japanese port tested positive for the coronavirus on Friday and thousands of passengers remained confined to their cabins, only allowed on deck briefly for fresh air.

The Diamond Princess, operated by Princess Cruises, was placed on a two-week quarantine on arriving at Yokohama on Monday after a man who disembarked in Hong Kong was diagnosed with the virus.
