Test results on Saturday confirmed three additional officers assigned to Naval Special Warfare who were training at Naval Base Kitsap have tested positive for COVID-19.

On March 19, Naval Special Warfare confirmed its first case of the virus with a sailor who was also at Naval Base Kitsap. A fifth member of NSW was also tested but results came back negative. According to a news release, all four positive cases are showing signs of improvement.

The four petty officers who have tested positive for the virus are currently isolated on base and are restricted in movement in accordance with the Centers for Disease Control and Prevention guidelines. Another member of the group who was in close contact with the sailors currently isn’t showing symptoms but is also being quarantined at NBK, the release stated. All members also remain in close contact with medical professionals.

Naval Special Warfare also stated they would not provide or confirm the rate of any of the four petty officers who tested positive for COVID-19 in support of operational security.

“U.S. Special Operations Command and the Navy are committed to taking every measure possible to protect the health of our force,” the release stated. “We remain in close coordination with local agencies, base tenant commands, and public health authorities to ensure the well-being of our personnel and the local community.”
