21 people aboard a cruise ship stranded off the coast of San Francisco tested positive for the new corona virus, Vice President Mike Pence said on Friday.
"Among the positives for coronavirus were 19 crew members and two passengers," said Pence, tasked by President Donald Trump to coordinate the US government's response to the outbreak.
Pence said the ship will be brought to a non-commercial dock this weekend and all 3,533 passengers and crew will be tested.
"We will test everyone on the ship and quarantine them if necessary," said Pence. "But with regard to the 1,100-strong crew, we assume that they will be quarantined on the ship."
The Grand Princess has been stranded off the San Francisco coast since Wednesday, when it was scheduled to moor, after it was found that two people who were on the ship during their previous trip had contracted the virus. One of them died later.
Pence said he believed the number of people infected in the crew was high, as they were likely exposed on two previous trips.
He added that he expects four million test kits to be delivered to countries affected by the virus by the end of next week.
Princess Cruises operates the Diamond Princess, the coronavirus-infested vessel that was detained off Japan last month and over 700 people tested positive and six died.
More than 200 people have been infected with the deadly virus in the United States, and 12 people have died, 11 of them in the state of Washington.
Worldwide, more than 3,000 people have died from the rapidly spreading virus, which has infected more than 100,000 people in around 85 countries.
