Wastewater surveillance has turned up proof of the most recent Omicron subvariant EG.5 in Kingston, however no official instances have been documented, in keeping with an area knowledgeable.
The COVID-19 variant present in native wastewater is decided to be extra infectious than the subvariants at present circulating, says Stephen Brown, co-director of the Queen’s University wastewater surveillance lab.
“Once it’s more infectious, then we expect it to eventually take over as the main variant just because people are going to catch it faster than the other ones,” Brown stated in an interview.
After the looks of the EG.5 variant in Ontario earlier in the summertime, the Queen’s University chemistry professor stated it was anticipated to be seen in Kingston sooner slightly than later.
But its look is much less trigger for alarm than when Omicron first made made it to the town again in late 2021.
“When Omicron first came in, it was really dramatically different than the previous types of COVID, which would have been the Delta variant,” Brown stated.
“It took over really quickly and people didn’t have a lot of immune protection, even if they had had COVID previously,” he continued.

Omicron was additionally the Kingston area’s first time coping with a lot of individuals being contaminated with COVID-19. Prior to its look, Kingston had remained comparatively unscathed in comparison with different components of the nation.
“When we were doing wastewater tracking, when Omicron came in, the wastewater virus levels went up like a factor of 10 and a couple of weeks,” Brown stated.
The Queen’s researcher stated that is at present not the case for the EG.5 subvariant.
“The overall amount of COVID in the wastewater is not increasing dramatically,” Brown stated.
He stated the quantity goes up slowly, which is to be anticipated when monitoring a barely extra contagious virus.
Brown stated total, the proof of the brand new subvariant shouldn’t be overly regarding, but it surely does present the advantage of doing this sort of analysis even after the pandemic has ended.
“We still have people dying from COVID and we will probably have an increase in the number of deaths from COVID in the fall as those levels go up and more infectious variants come in,” he stated.
“It’s still an important issue, even if everyone on the street isn’t talking about it the way they were a year or two ago,” he stated.
Brown stated that his lab shall be monitoring for each the flu and COVID this fall as a way to assist public well being officers sort out each viruses within the colder months.
