An outbreak of the COVID variant that was first identified in Brazil has been declared at a workplace in the Calgary zone, as variant cases continue to spread in Alberta.
Dr. Deena Hinshaw, Alberta’s chief medical officer of health, did not disclose the location of the local workplace outbreak Monday but said it had been linked to five cases of COVID-19, including one confirmed case of the highly contagious P.1 strain. This is one of two concerning outbreaks of the P.1 variant reported by Hinshaw.
Cases of the P.1 strain have also been linked to an outbreak at three PTW Energy Services work sites in Alberta Health Services’ North and Central zones. A traveller returning to Alberta from out of province brought the variant to work and, because employees travel between sites, the outbreak has spread to 26 staff and members of their households. Only three of those cases are confirmed to be the P.1 strain; however, Hinshaw said this is likely to increase as more test results arrive.
“AHS has been working with the operator and cases to ensure anyone at risk of exposure is offered testing and quarantines to limit the spread,” Hinshaw said on her Twitter account Monday.
Workers who may have been exposed at other sites, including work sites in the Calgary zone, are being asked to get tested. No P.1 cases have been connected to these work sites in the Calgary zone to date, according to Alberta Health spokesman Tom McMillan.
In a statement provided to Postmedia, PTW Energy Services COO Kerri Beuk confirmed the three variant cases were at the Drayton Valley, Edson and Hinton offices.
“Our thoughts are with our employees and their families at this time as our employees isolate and focus on their health and recovery,” the statement reads.
Early research suggests the P.1 variant is up to 2.5 times more transmissible than the currently dominant strain.
Hinshaw thanked Albertans for their patience as Alberta Health looked into the outbreaks. She did not release the locations of either variant outbreak, though an updated list is expected to include those that meet the provincial reporting threshold on Tuesday.
“These investigations are complex and it’s important that we ensure information is accurate and that anyone at risk is directly contacted before sharing details,” she wrote.
“We also must balance the public desire for info with protecting patient confidentiality.”
