Princess Cruises confirmed that one of its cruise liners, the Ruby Princess, reported a COVID-19 outbreak before docking in San Francisco.

The cruise operator requires passengers and crew members to be fully vaccinated for COVID-19, which is caused by the CCP (Chinese Communist Party) virus. Princess Cruises also mandates passengers to show a negative COVID-19 test and proof of vaccination to board, according to its website.

Those who tested positive were "isolated and quarantined while monitored and cared for by our shipboard medical team," Princess Cruises said in a statement to news outlets Monday. It did not say how many people tested positive or when they tested positive during the cruise.

"They were all asymptomatic or only mildly symptomatic," the firm said. Some of the passengers who contracted the CCP virus did not finish their quarantine and were either sent home or "were provided with accommodations ashore to hotels coordinated in advance for isolation and quarantine," the statement added.
