Covid variants are considered more dangerous than the original version of the virus, as they are more transmissible, deadly or may exceed some protections against the vaccine – Copyright AFP / File DOUGLAS MAGNO
The latest variant of coronavirus concern, which experts say appears to be more transmissible and cause more severe symptoms than other variants, could become the dominant strain of the virus in Ontario in a few weeks.
The coronavirus variant labeled a Delta variant by the World Health Organization (WHO), is one of two variants of the B.1.617 family first identified in India and is thought to be from 30 to almost 100 percent more transmissible.
“It simply came to our notice then [new] the variant may be 60 percent more transmissible than Alpha [‘U.K.’] variant, ”epidemiologist Neil Ferguson he said The guardian.
The Delta variant has now spread to 62 countries, including the United States and Canada. In accordance with Public Health England (PHE), on Thursday, said coronavirus variant B.1.617.2 (Delta variant) is now believed to be dominant in the UK;
The PHE warned that although more data are needed, early findings showed that variant B.1.617.2 or “Delta” was more likely to cause serious illness than variant B.1.1.7 or “Alpha”. , which had been dominant in the UK since it was first detected in the south-east of England last autumn, informs CNN.
And with the number of new cases in England, identified primarily as the Delta variant, and with most unvaccinated patients, serious doubts arise about the plan to remove all remaining coronavirus restrictions in England on June 21st.
“The virus definitely increases your game”
This was stated by Dr. Peter Juni, Scientific Director of the Scientific Advisory Board of the Government of Ontario CTV news Wednesday the Delta variant was probably 50 percent more transmissible than the Alpha variant, which fed Canada’s third coronavirus wave.
He added that the Alpha variant was much more infectious than the SARS-CoV-2 strain that had originally been prevalent in Canada. “The virus is definitely increasing their game,” he said.
At a news conference Wednesday, Dr. Lawrence Loh, the health doctor in the Peel region on the outskirts of Toronto, said cases of B.1.617 “quickly replace” B.1.117 as the most prevalent form of virus locally.
He also noted that modeling data indicate an imminent increase in cases. “The trends that are being observed are worrisome,” he told reporters.
“Preliminary data suggests that … within a month, the delta variant will be the dominant strain in our region, with the rest of Ontario weeks back.”
The importance of getting completely vaccinated
Researcher Zeynep Tufekci wrote an article for The New York Times titled “The deadliest phase of COVID may arrive here soon”On May 28. Something he wrote stands out like a sore thumb.
“A variant with more transmissibility is a huge danger to people without immunity from vaccination or previous infection, even if the variant is not more deadly than previous versions of the virus … A more transmissible variant can burn to through such an immunologically naive population. very fast“.Zeynep Tufekci
And this is particularly interesting: British researchers have found that two doses of a COVID-19 vaccine appear to be slightly less effective against the Delta variant (providing 81% protection, compared to 87% against the dominant UK variant).
But for many people who have only received a two-dose vaccine, the protection drops to only 33 percent.
“If that’s accurate,” he writes Intelligence, “That means [the Delta variant] it may be the variant that currently poses the greatest threat to partially vaccinated populations worldwide. ”
