The WJC Event Executive Committee said in a statement, "The Event Medical Team and Executive Committee will ensure that the affected individuals get the care they require. Our No. 1 priority is the health of the individuals and to ensure that we isolate these cases to keep the entire community and event safe.
"The medical plan was built with a quarantine period for participating teams before departure and upon arrival in Canada. We worked closely with Alberta Health Services and the Canadian government to build a plan that is endorsed by medical experts and supported by all levels of government and health.
"... All other teams will be released from the quarantine period once all test results have been confirmed. Among the tests conducted on game officials as well as IIHF, local organizing committee, and broadcasting staff there have been no confirmed positive cases reported."
