A New Type Of COVID-19 Delta Variant Is Confirmed In BC & Here's What We Know About It

The first cases of a new strain of the COVID-19 Delta variant have been confirmed in B.C.

In a press conference, Provincial Health Officer Dr. Bonnie Henry announced that they had identified the cases of what is called the AY.4.2 strain of the Delta variant.

She said, "We are continuing to follow the whole genome sequencing and making sure we're aware of what strains are being transmitted here in British Columbia."

The province is also tracking two other strains of the Delta variant — called AY.25 and AY.27 — which currently make up around two-thirds of the province's cases.

How Does This New Strain Happen?

Dr. Henry said, "All virusesmutate. Weknowthat. Anddevelopmentofthesenewlineages,whichareuniquetogeographicareas,arereallyexpectedovertimewhenwehaveongoingtransmissioninourcommunities."

Is It Making People Sicker?

She said that while this new strain is not yet classified as a variant of concern, they are monitoring how it affects those who are infected.

What Other Physicians Are Saying

Earlier this month, during a physician town hall, Dr. Jessica Minion, a medical microbiologist with the Saskatchewan Health Authority, told fellow doctors about two new strains of the Delta variant circulating in western Canada called AY.25 and AY.27.

She told the town hall, "We warned people that uncontrolled spread is going to lead to evolution of the virus. You give it enough opportunities to pass through enough people you're going to get something unique to western Canada and this is what it is."

Health Canada has a robust website with all the latest information on COVID-19 vaccines and can answer any questions you may have.
