Canada’s chief public health officer Dr Theresa Tam said on Friday there were just over 2,000 confirmed cases of the variant.
Just three days ago, the Public Health Agency of Canada (PHAC) told The Canadian Press that there were 1,187 confirmed cases.
The Delta variant is now in all provinces and at least one of our territoriesMs. Tam told the House of Commons health committee.
Of course, as with all coronavirus cases, we may not be aware of all of the cases that have occurred in Canada, hence my precautionary warning and the need for two doses of the vaccine at most. large number of people possible.
The variant was first identified in India, but it has now become the dominant strain in the UK, where it is spreading rapidly, mainly among unvaccinated people.
It is believed to be at least 1.5 times more contagious than the Alpha variant first identified in the UK. Alpha is, so far, the dominant variant in Canada, with more than 216,000 confirmed cases.
Public Health England reported on Friday that the number of confirmed cases of the Delta in the UK increased by 80% last week, to nearly 76,000. UK Prime Minister Boris Johnson has had to delay plans to completely lift all public health restrictions next week.
Dr Tam pointed out that Delta is of concern, because one dose of vaccine is not as effective against this variant. In addition, it shows the need for Canada to continue to accelerate the pace of administration of the second doses.
Two doses of the vaccines used by Canada are estimated to provide very good protection against Delta, and one dose has been shown to be effective in preventing serious illness.
The Delta variant is becoming the majority worldwide, the chief scientist of the World Health Organization (WHO) said on Friday. The United Kingdom and Russia, in particular, are facing an upsurge in contamination by this mutation of SARS-CoV-2.
All provinces are warning against the existence of the Delta. It is believed to be the cause of a major outbreak in the Kashechewan First Nation in northern Ontario; it sparked an outbreak at a Calgary hospital and it worries health officials in Waterloo, Ont., an area that has suddenly become the province’s COVID-19 hotspot.
In Quebec, there are 35 cases of the Delta variant, especially in Montreal (21) and Montérégie (7), according to data on the website of the National Institute of Public Health of Quebec as of Friday.
However, data on the Delta in Canada is limited and has not yet been added to the Health Canada website reporting variant cases. Only Alpha, Beta (the B.1.351 variant identified in South Africa) and Gamma (the P. 1 variant identified for the first time in Brazil) are listed on the site.
This site also hasn’t adjusted the names to use the Greek alphabet now preferred by the World Health Organization. A spokesperson for Health Canada told The Canadian Press in early June that the Delta would be added to it.
in the next weeks.
Asked again this week, she provided the same answer.
Dr Howard Njoo, deputy chief public health officer, said collecting data on the variant had not been easy and there was a backlog in reporting.
There are obviously issues we need to work on, he said, noting that he
there are probably more cases than what was reported.
He said, however, that data provinces and territories hold suggest that most cases of Delta are in people who are not vaccinated.
