The Marine, who is an officer assigned to the service’s headquarters office, is in isolation at his home after his wife, according to a report, began to show symptoms of the virus.
“Once he became ill, he contacted his assigned medical facility,” Capt. Joseph Butterfield told Military Times. “His workspace has been cleaned by a Pentagon response team and a thorough contact investigation is underway to mitigate risk and preserve the health of our Marines, civilians, and families.”
His last day at the Pentagon was March 13.
The Department of Defense (DOD) said his workspace was cleaned by a response team.
The Pentagon is investigating the Marine’s contact impact before his diagnosis.
Two other defense workers who had visited the Pentagon have tested positive, but they were not assigned to the building.
As of Wednesday morning, DOD reported 453 COVID-19 cases among service members, civilians, dependents and contractors, 227 of whom are troops.
