The first sailor to test positive was co-monitored by the ship as he showed symptoms, according to Pentagon spokesman Jonathan Hoffman and tested positive at a medical treatment facility in San Antonio.
"The sailor is stable and receives care at a medical treatment facility in San Antonio, Texas," the Navy said in a statement Friday.
There have since been other sailors on the ship that have tested positive and the Navy's statement added that "testing continues, and we expect more cases."
"They are preparing to return to the port, where they will make an effort to clean the ship. They will remove part of the crew from the ship. And work to get everyone back to health and get the ship back to sea," she said. Hoffman.
An eight-member Navy medical team has flown out to the ship, conducting contact tracking and isolation of people who may have been exposed, according to Hoffman.
