Uruguay's foreign ministry said there is a "high number of positive (coronavirus) results" aboard the Australian cruise ship Greg Mortimer, currently docked off the coast of the South American country.
The ship's operator announced earlier today that at least 81 passengers and crew on the ship have tested positive.
Six passengers on the ship required specialized care and were transferred to medical centers in the capital city Montevideo for treatment, said a statement from the ministry.
"The remainder of the passengers and crew have been classified as asymptomatic or with mild symptoms," the statement said.
The ministry also said that passengers will not be able to disembark the ship unless a humanitarian effort can be organized.
The cruise ship originally had 128 passengers and 83 crew members onboard. More than 120 passengers and staff onboard were tested for Covid-19. Some 45 have tested negative, and another 90 test results are expected to be processed over the next 12 to 24 hours.
