Attendees of a youth hockey tournament in Anchorage are being advised by health officials to either isolate or quarantine following a cluster of COVID-19 cases connected to the tournament.

The Termination Dust tournament was attended by teams from Juneau; Anchorage; Eagle River and Chugiak; Wasilla and Palmer; and Kenai and Soldotna, Anchorage Health Department announced. Juneau Public Health recommends attendees of the tournament held Oct. 2-4 from Juneau call their doctor or 586-6000 to get tested, City and Borough of Juneau said in a news release.

Anchorage Health Department urged attendees who do not have symptoms to quarantine for 14 days, except to get tested, and those with symptoms to isolate for 10 days, except to get tested.

Dr. Janet Johnston, the department’s epidemiologist, told the Associated Press that means the department is recommending up to 300 isolate or quarantine.

Heather Harris, the department’s director, could not provide “concrete” numbers of positive cases associated with the tournament. She told the AP that tournament organizers said they tried to enforce masking guidelines and kept a contact log of participants.

Contact trace investigations indicated “significant close contact in indoor spaces, including locker rooms, with inconsistent use of face coverings,” the city health department said in a release.
