Canada contracts Omicron COVID-19 variant from Nigerian travellers

Canada has detected its first cases of the new Omicron strain of Covid in two people who had travelled recently to Nigeria, TopNaija reports.

The government of Ontario confirmed that the two cases are in the capital, Ottawa.

Federal and Ontario provincial officials said both patients are in isolation while public health authorities trace their possible contacts.

“I was informed today by the Public Health Agency of Canada that testing and monitoring of COVID-19 cases has confirmed two cases of the Omicron variant of concern in Ontario,” Health Minister Jean-Yves Duclos said in a statement.

“As the monitoring and testing continues, it is expected that other cases of this variant will be found in Canada,” he was quoted as saying by France24.com.

But Federal Government had claimed that the new COVID-19 variant was not in Nigeria yet.

The Director-General of the Nigeria Centre for Disease Control, Dr Ifedayo Adetifa, said in a statement on Sunday that the centre is prioritising sequencing of recently accrued samples from SARS-COV-2 positive travellers from all countries, especially those from countries that have reported the Omicron variant already.

On Friday, Canada banned travel from seven African countries over concerns about the spread of the Omicron strain. Nigeria was not one of them.

The United States top infectious disease official, Dr Anthony Fauci told President Joe Biden on Sunday it will take about two weeks to have definitive information on the Omicron variant.

Biden, returning to Washington following the Thanksgiving holiday weekend, was briefed in person by his coronavirus response team on Sunday afternoon as officials expect the new variant to reach the United States despite an impending ban on travellers from Southern Africa, where it was first detected.

Fauci said he believes existing vaccines are likely to provide “a degree of protection against severe cases of COVID”, and officials reiterated their recommendation for vaccinated Americans to get booster shots, according to a readout of the briefing.

What is the Omicron COVID-19 variant?

This Omicron COVID-19 variant has a large number of mutations, some of which are concerning. Preliminary evidence suggests an increased risk of reinfection with this variant, as compared to other VOCs. The number of cases of this variant appears to be increasing in almost all provinces in South Africa. Current SARS-CoV-2 PCR diagnostics continue to detect this variant. Several labs have indicated that for one widely used PCR test, one of the three target genes is not detected (called S gene dropout or S gene target failure) and this test can therefore be used as marker for this variant, pending sequencing confirmation. Using this approach, this variant has been detected at faster rates than previous surges in infection, suggesting that this variant may have a growth advantage.
