The person who tested positive was one of the evacuees from the quarantined Diamond Princess cruise ship in Japan. 

Officials said the patient was transferred from the base on Wednesday. They aren't disclosing details about the patient or the hospital for privacy concerns. 

An agreement with the Department of Defense and CDC requires any evacuee who tests positive to be moved from the base.
