The aircraft carrier USS Theodore Roosevelt is docked at Naval Base Guam in Apra Harbor on April 10, 2020. At least 416 sailors aboard the aircraft carrier, or 8.6 percent of the ships crew of 4,800, have tested positive for the novel coronavirus, with the numbers increasing daily.

WASHINGTON — A U.S. Navy sailor assigned to the coronavirus-stricken USS Theodore Roosevelt aircraft carrier died Monday from the disease after testing positive last month, the service confirmed in a statement.

"At approximately 8:30 a.m., Apr. 9, the Sailor was found unresponsive during a daily medical check. While Naval Base Guam emergency responders were notified, CPR was administered by fellow Sailors and onsite medical team in the house. The Sailor was transferred to U.S. Naval Hospital Guam where the Sailor was moved to the Intensive Care Unit. The Sailor was declared deceased April 13," the Navy wrote in a Monday statement.

The sailor's death is the first for one of the U.S. Navy's vessels at sea and comes as nearly 600 sailors on the ship tested positive for the coronavirus.

"Our thoughts are with the family of the USS Theodore Roosevelt sailor who lost his battle with the virus today," Secretary of Defense Mark Esper said in a statement. "We remain committed to protecting our personnel and their families while continuing to assist in defeating this outbreak."

Adm. Mike Gilday, chief of naval operations, said in a statement that "We mourn the loss of the Sailor from USS Theodore Roosevelt who died today, and we stand alongside their family, loved ones, and shipmates as they grieve. This is a great loss for the ship and for our Navy. My deepest sympathy goes out the family, and we pledge our full support to the ship and crew as they continue their fight against the coronavirus."

The growing outbreak threatening the crew aboard the Roosevelt was foreshadowed in a leaked letter penned last month by the ship's captain.
