Omicron COVID-19 variant likely to re-infect ‘over and over again,’ experts say

Although COVID-19 cases are declining across the country, chances of getting re-infected with the virus are still possible — especially from the omicron variant — experts say.

“As long as it’s transmitting in the community, there’s always a possibility,” Stephen Hoption Cann, clinical professor at the University of British Columbia’s school of population and public health, told Global News.

Getting Omicron more than once also seems more likely than with other variants.

“The Omicron variant, in particular, seems to be one that will re-infect people over and over again,” Kelly McNagny, professor of medical genetics at the University of British Columbia’s school for biomedical engineering, told Global News.

“It’s a little bit more like the common cold virus that tends to infect the upper airways, which is a place where you tend not to develop strong immunity easily.”

Unlike Omicron, other variants of the virus tend to infect someone deeper in the airways, according to McNagny. “I think that gave you a bit more protection,” he said.

Lisa Glover, assistant director of Alberta Health, also says “reinfections have increased since Omicron has become the dominant variant.”

“The risk of reinfection from Omicron is much higher than any other previous variant,” Glover told Global News.

“A major factor that increases the likelihood of reinfection is the waning immunity from a previous infection or not being fully up-to-date with COVID-19 immunization, including additional doses,” she said.

Regardless of the variant, McNagny says being vaccinated will give a higher level of protection against reinfection. Aside from vaccination, bringing back mask

Although COVID-19 cases are declining across the country, chances of getting re-infected with the virus are still possible — especially from the omicron variant — experts say.
COVID-19 cases are on the decline, but more and more Canadians are getting sick with the flu across the country, Canada’s top public health officer said Friday.“We’re seeing influenza activity increasing up to the seasonal threshold despite the opposite trends being expected this time of year,” Dr. Theresa Tam, the nation’s chief public health officer,told reporters during a federal COVID-19 update.Without many COVID-19 health mandates like masking in effect in most places across the country, cases of the flu have increased, according to Tam.“One of the things we’ve learned about the use of public health measures for COVID-19 in the past two years is that they were also effective in reducing the prevalence of other infectious diseases.

Housing affordability in Ontario has eroded faster than any province amid COVID-19: report
Housing affordability in Ontario has eroded at a rate not seen in half a century over the course of the COVID-19 pandemic, a new report suggests, while home prices skyrocketed by 44 per cent across Doug Ford’s premiership.The new report by Generation Squeeze found that with current home prices, a new homebuyer would have to work full-time for nearly 22 years to save up enough money for a 20 per cent down payment on a home — up from 15 years in late 2019.“Ontario has just completely lost control of housing,” said Paul Kershaw, an associate professor at the University of British Columbia and the founder of Generation Squeeze, which studies housing affordability and standard of living across Canada.“We’ve never seen anything like this before in any province at any time in the last 50 years.” ‘I’ll never be able to afford property’: Housing costs key issue for Ontario voters The report, citing Canadian Real Estate Association data, found the average price for a home in Ontario rose to $871,688 by 2021, up 44 per cent from the inflation-adjusted price in 2018 — the year Ford was sworn in as premier.Meanwhile, wages have stagnated, particularly for the typical 25-to-34-year-old, which the report argues has led to “lost work” for those trying to save for a down payment.Over the first two years of the pandemic, Kershaw says those young Ontario residents have lost the value of six years of work that would otherwise be put toward home ownership.

COVID-19 won’t disappear and provinces need to ‘evolve,’ says Canada’s top doctor
COVID-19 pandemic, British Columbia’s premier has said he’s looking for ways to balance public protection with individual freedom.In a Friday press conference after a meeting of all Canadian premiers, John Horgan said he and other provincial and territorial leaders, discussed interprovincial travel rights as the Omicron variant continues to impact public health restrictions.“As we come to this place of moving in the next number of weeks to potentially endemic rather than pandemic, we need to reimagine the tools at our disposal as citizens and as provinces, and as a federal government is,” said Horgan.“How do we maximize our ability to protect people, which is our obligation, but also to ensure that their liberties are intact and they can make choices for themselves? It’s a fine balance and we’re all working together on how do we get there?” Canadian premiers push for boost in health-care funding from Ottawa In a news conference Friday, Canada’s chief public health officer Dr. Theresa Tam said that as Canada emerges from the “Omicron wave,” it’s important for governments to recognize that the virus isn’t going to disappear.“We need to be able to address the ongoing presence of the SARS‑CoV‑2 virus in a more sustainable way,” she said.“The virus will continue to evolve so we need to also continue to evolve our measures, recognizing that further waves will occur.”Her comments come as two provinces, Alberta and Saskatchewan, have announced intentions to end most or all COVID-19 restrictions.
