Acting Secretary of the Navy Thomas Modly said Tuesday that three cases were detected on the Theodore Roosevelt. He said those were the first cases on a deployed ship and that the affected personnel were awaiting transfer off the carrier.
The "Big Stick," which carries some 5,000 crew, visited Vietnam earlier this month. The Navy's top uniformed officer said Tuesday that it wasn't clear if the cases stemmed from that visit.
"Whenever we have a positive on any ship ... we're doing the forensics on each one of those cases to try and understand what kind of best practices, or the do's and the don'ts, that we can quickly promulgate fleet-wide," Chief of Naval Operations Adm. Michael Gilday said at the Pentagon.
Asked about specific policy changes, Gilday said, "we're on it" but "no specifics yet."
