Hinshaw tweeted Saturday that Alberta Health is investigating a “significant COVID-19 outbreak” in the province involving the P.1 variant linked to a returning traveller.
“Health officials are working hard to limit future spread and reaching out directly to those at risk of exposure,” she said.
“AHS will ensure that anyone at risk is isolated, offered testing twice and connected with supports if needed.”
Hinshaw said the province will update Albertans about the outbreak on Monday.
“We are all protecting each other, so let’s all please keep making safe choices, following the health measures in place and preventing the spread of COVID-19,” she said.
