"The first patient transported is already improving and will self-isolate. We are taking every precaution to ensure we identify, isolate, and prevent any further spread onboard the ship,” said Rear Admiral Don Gabrielson, commander U.S. Naval Forces Southern Command/U.S. 4th Fleet. “Our medical team continues coordinating with the ship and our focus is the safety and well-being of every Sailor.”

The aircraft carrier Theodore Roosevelt limped into Guam with an outbreak on board nearly a month ago on March 27. With TR headed to Guam, the destroyer Kidd was dispatched to the eastern Pacific as part of the Pentagon's plan to ramp up the counter-drug mission recently announced at the White House earlier this month.

On April 1st at the White House, President Trump announced the U.S. military would be sending more warships, including "Navy destroyers" to ramp up counter-drug operations. USS Kidd was not mentioned specifically during the White House press conference attended by Defense Secretary Esper and other top Pentagon brass.

"We’re deploying additional Navy destroyers, combat ships, aircraft, and helicopters; Coast Guard cutters; and Air Force surveillance aircraft, doubling our capabilities in the region," Trump said.

Defense Secretary Esper later said there was "no risk" to the fleet while talking about the reinforcements being sent to the counter-drug mission:

"We felt that there was no risk to the fleet, to our operations to free up, in this case, naval ships. We also freed up aircraft and other assets to apply them to this presidential priority."

The chairman of the Joint Chiefs of Staff appeared at the White House alongside the defense secretary.

"We’re at war with COVID-19, we’re at war with terrorists, and we are at war with the drug cartels as well," Army Gen. Mark Milley added.
