A brand new extremely transmittable variant of COVID-19 originating in South Africa has led Canada to a journey ban, elevating considerations that this might result in a rise in native instances.
The brand new variant, referred to as Omicron, appeared for the primary time in South Africa and, based on the World Well being Group, has coincided with a steep improve within the variety of COVID-19 instances on this area in latest weeks.
The Canadian journey ban introduced on Friday (November 26) applies to foreigners who’ve crossed an inventory of seven international locations previously 14 days, together with South Africa, Mozambique, Botswana, Zimbabwe, Lesotho, Namibia and Eswatini.

After that, they’ll isolate themselves at dwelling till they check unfavorable 10 days after arrival.
What menace does Omicron pose in BC?
Thus far, no instances of the Omicron variant have been detected in Canada.
However dr. Jeffrey Pleasure, Assistant Professor, Division of Drugs on the College of British Columbia (UBC), informed Vancouver Is Superior that the journey ban is unlikely to stop the brand new variant in BC
“Journey measures will purchase us a while to organize and this is essential, however such measures are unlikely to stop their closing arrival on our shores,” he mentioned.
And as soon as the variant is found domestically, Pleasure notes that it’ll probably unfold shortly. “It’s spreading a lot quicker in South Africa than the Delta variant, and right here in British Columbia it would probably have an identical fee of unfold.”
Pleasure informed VIA in June that he’d hearken to Dr. Anthony Fauci, the USA’ main infectious illness professional, wholeheartedly agrees with the Delta variant. Fauci had famous that “the Delta variant is presently the best menace within the US in our try and eradicate COVID-19.”
By way of transferability, Pleasure had emphasised that the Delta variant is considerably extra transferable than different strains. For instance, if the alpha variant (initially found within the UK) is about 50 p.c extra transmissible than the pressure initially found in Wuhan, then the delta variant is sort of twice as excessive.
Since then, Delta has grow to be the predominant pressure in BC and all over the world, representing the overwhelming majority of instances.
Pleasure now emphasizes that the Omicron variant may pose a good higher threat.
“This variant is completely different as a result of additionally it is rather more transmissible than another variant thus far and likewise has numerous mutations that make it extra resistant to evasive,” he defined.
“We don’t but know for certain what the extent of vaccine resistance is or how efficient the vaccines will probably be.
“A few of these mutations are linked to resistance to neutralizing antibodies and bypassing innate immunity.”
Since a lot remains to be unknown about Omicron, Pleasure emphasizes that it’s nonetheless “a little bit too early” to say how nice the menace is. On the one hand, he states that “we nonetheless do not know elementary issues about this variant. For instance, whether or not it causes extra severe sicknesses or not.”
Regardless, the truth that it’s considerably “extra transferable implies that the case numbers would probably be a lot greater”.
BC well being officers reply to the Omicron menace
Provincial Well being Officer Dr. Bonnie Henry and Well being Secretary Adrian Dix introduced their help for the federal journey ban in a press release launched Friday afternoon. They state that the precautionary measure is “prudent” however stress that there isn’t a proof that the brand new variant is in BC. was launched
“The BC Heart for Illness Management’s public well being laboratory has sequenced over 90,000 virus isolates in BC and can proceed to make use of full genome sequencing to watch all circulating variants in BC, together with this new VOC Omicron,” the assertion mentioned .
“As well as, Public Well being will work with the Well being Canada Authority and Canada Border Safety Company to determine anybody who has just lately returned from the areas of concern to rearrange exams and guarantee they’re protected.”
Earlier this month, well being officers introduced that the primary instances of the Delta variant of the AY.4.2 pressure had been found in BC.
Whereas well being officers in Europe failed to note that the pressure precipitated decreased efficacy in opposition to vaccines, Henry famous that they did discover “barely elevated transmissibility”.
