There have been 221 cases of variants reported in Alberta, with 214 of those identified as the B.1.1.7 variant and seven of those identified as the B.1.351 variant first found in South Africa.
Up until December 2020, about 1% of Alberta's COVID-19 patients didn't pick up the phone when contact tracers called them.
Unfortunately, there is a but, and that is the wildcard of what happens with the spread of new COVID-19 variants.
"I am particularly concerned with the growing number of cases not linked to travel", Hinshaw said.
According to the Centre of Health Informatics at the University of Calgary, new cases have dropped 19 per cent week-over-week in Alberta.
In Ontario, the rise of variants could potentially delay reopening plans.
Variants represent approximately 0.5 per cent of new cases in Alberta.
Dr. Hinshaw provided the COVID-19 update for Tuesday, February 16.
"We will be watching closely in the days to come to see if this (is an) isolated finding or concerning trend", Hinshaw said.
Overall, half the variant cases diagnosed in the province were linked to travel or the close contact of a traveller.
A statement from the labour group links to a letter that Alberta Health Services wrote to Olymel last week, which says on-site testing suggests one in five workers may have been infected.
"We have implemented those interventions where we've seen the risks to be highest, and now we're considering whether or not there may be additional pieces to further reduce risk of transmission".
