Ontario Reports Fifth Case of Omicron Coronavirus Variant in Durham Region – .


A fifth case of the Omicron coronavirus variant was confirmed by health officials in Durham Region on Thursday.

Durham Region Public Health says the Omicron positive person is a close contact of a person recently returned to Canada from southern Africa.

“The Department of Health is also monitoring other investigated COVID-19 cases for the Omicron variant based on travel history and is working with the province to monitor COVID-19 variants of concern,” including Delta and Omicron. “

Earlier this week, Ontario officials confirmed four more cases of the Omicron variant in Ottawa and said nearly 400 people who returned to Ontario from southern Africa in the past two weeks were in mandatory self-quarantine.

The Durham report represents the first known example of local transmission of the Omicron variant (B.1.1.529) confirmed in the province to date.

Chief Medical Officer of Health Dr Kieran Moore said there are now 1,800 people under mandatory self-isolation who have recently arrived in Canada from one of ten African countries where the Trudeau government has now banned to all foreigners to arrive.

He said it was only a matter of time before more cases were detected in the province.

The province is now preparing to perform full genomic sequencing on all COVID-19 positive samples and the federal government has adopted several new measures to tighten controls on international travel.

Moore said the province is also resurrecting adjustments to the standard COVID-19 PCR test so that it can detect the S-Gene deletion present in most of the Omicron samples collected.

S-Gene suppression or S-Gene target failure was used across the province to track the spread of the Alpha coronavirus variant (B.1.1.7) in early 2021.

Moore said the arrival of Omicron adds new haste to the province’s ongoing third-dose campaign, now reduced to anyone aged 50 and over.

“When Delta passed Alpha, it took 4 months for that to happen – we could have a shorter window for Omicron given that it’s more transmissible,” he said.

He said it was still not clear whether existing vaccines would provide a high degree of protection against serious illnesses caused by Omicron.

“We don’t expect a 100% loss in vaccine efficacy,” he said.
