In Canada, nearly 3.5 million cases of coronavirus have been reported, which is nine percent of the total population – but what about the rest? Experts say that due diligence with public health measures, the power of vaccination and a little luck have kept many free from COVID-19.

“In order not to catch COVID, you have to be careful, meticulously careful and also lucky,” said Colin Furness, an infection epidemiologist and assistant professor at the University of Toronto. Your location and lifestyle may increase your chances of catching COVID-19, with studies showing that marginalized communities are at higher risk of infection.

This may also explain why people have different reactions to the virus and have different symptoms.

“There are some diseases that are clearly linked to one gene, but in many cases, they are much more complex and there can be multiple pathways,” Furness said. There are seven known coronaviruses that can infect humans, including the common cold.

A study published in Nature Communications in January suggested that having higher levels of pre-existing T cells produced by the body when infected with other coronaviruses may protect against COVID-19 infection.

Another study published in November 2021 in the journal Nature also showed that UK healthcare workers who repeatedly tested negative for COVID-19 were able to repel the virus due to the presence of T cells from exposure to previous seasons. coronaviruses.

Getting to the bottom of this question could be a “real game changer” in fighting the pandemic, Furness said. “It is possible that, if we could understand on what basis some people are immune, we could develop effective drugs. “We may also be able to identify who is at high risk.” © 2022 Global News, part of Corus Entertainment Inc.
