The flip comes after months of low transmission of the virus, which continues to mutate and has just lately spawned two variants — EG.5, a subvariant of Omicron, and BA.2.86 — which have captured the eye of scientists.
“We’re starting to see an uptick in cases after a pretty long decline. We saw really an impressive drop in the number of infections that started right at the end of 2022 and continued to all the way to the middle of this summer,” Dr. Fahad Razak, a professor on the University of Toronto and inside medication doctor at St. Michael’s Hospital, informed Global News Wednesday.
“Over the last few weeks, we’ve started to see that rise again … It’s that expected rise. I think nothing of that is surprising to any of us that, after a period of decline as the virus continues to mutate, you’ll have a period where you start to have that increase again.”
Dr. Jesse Papenburg, a pediatric infectious illness specialist on the Montreal Children’s Hospital of the McGill University Health Centre, shared related sentiments with Global News earlier this month.

There is way to find out about each variants, however the World Health Organization has labelled E.G5 as a “variant of interest” and BA.2.86 a “variant under monitoring.”
“Public Health Agency of Canada scientists, along with national and international experts, are actively monitoring and evaluating BA.2.86 lineages,” a Health Canada spokesperson informed Global News in an announcement Friday.

“My expectation is that after seeing a pretty long period of declining COVID numbers, we’ll start to see that uptick now heading into the fall and winter,” Razak mentioned.
“We are likely at the start of a new wave here. … how big it will be remains unknown.”
