Canada in ‘better shape’ than predicted in face of XBB.1.5, expert suggests

Canada in ‘better shape’ than predicted in face of XBB.1.5, expert suggests

Global News
Sunday, January 29, 2023 12:17:46 PM UTC

The potential for a rise in infections and reinfections from the new COVID-19 variant XBB.1.5 in Canada appears to be in the 'rearview mirror,' according to one expert.

The potential for a rise in infections and reinfections from the new COVID-19 variant XBB.1.5 appears to be in the “rearview mirror,” according to one expert.

University of Toronto epidemiologist Prabhat Jha told Global News that he is “cautiously optimistic” as the variant nicknamed “Kraken” doesn’t appear to be leading to a big increase in hospitalizations.

“If (XBB.1.5) causes reinfections in people or new infections in the uninfected, then we could have a problem,” he said. “But if that were going to happen, it should have happened by now.

“I’m cautiously optimistic it’s mostly in the rearview mirror.”

While infection data is not as compressive as at the beginning of the pandemic due to governments not participating in active collection anymore, Jha said that wastewater indications have been encouraging, based on patterns he is seeing and what has happened in the past.

XBB.1.5 is essentially the “niece or nephew” of the main Omicron strains, such as BA.4 and BA.5, that were circulating in August and onward, Jha said. Its symptoms are flu-like, similar to Omicron, but do not seem to include the earlier COVID symptom of loss of smell.

Dr. Theresa Tam, Canada’s top doctor, said earlier in January that it does not appear XBB.1.5 has more severe symptoms. However, the World Health Organization has said XBB.1.5 is the “most transmissible” variant so far.

Jha attributes the better-than-expected outlook on “hybrid immunity” from people both getting infected with COVID-19 and receiving vaccination. He said this has created an “immunity wall” that has been more effective than experts had previously hoped.
