WASHINGTON — Five sailors on the U.S. aircraft carrier sidelined in Guam due to a COVID-19 outbreak have tested positive for the virus for the second time and have been taken off the ship, according to the Navy.
The resurgence of the virus in the five sailors on the USS Theodore Roosevelt underscores the befuddling behavior of the highly contagious virus and raises questions about how troops that test positive can be reintegrated into the military, particularly on ships. 
All five sailors had previously tested positive and had gone through at least two weeks of isolation. As part of the process, they all had to test negative twice in a row, with the tests separated by at least a day or two before they were allowed to go back to the ship.
The Roosevelt has been at port in Guam since late March after the outbreak of the virus was discovered. More than 4,000 of the 4,800 crew members have gone ashore since then for quarantine or isolation. Earlier this month hundreds of sailors began returning to the ship, in coordinated waves, to get ready to set sail again.
