The XBB.1.5 variant is currently responsible for more than 40% of COVID-19 infections in the United States, according to the Centers for Disease Control and Prevention (Centers for Disease Control and Prevention (CDC)).
It is part of the long line of variants that emerged from the Omicron wave early last year.says Dr. Fahad Razak, the former scientific director of the Ontario Scientific Advisory Group on COVID-19.
According to the epidemiologist, the infectiousness of this subvariant is still unknown, but there is no indication that it has more severe symptoms than other Omicron subvariants.
Windsor hit first?
According to data from CDCfive counties in Michigan have high levels of COVID-19 infections, while Wayne County, which includes the city of Detroit, has an average threshold of infections.
The border town of Windsor is usually the first Canadian region to feel the effects of a new wave in the United States, according to Dr Razak.
This is statistically where you would expect infections to spill over from the US first.he explains.
According to data from the Public Health Agency of Canada (PHAC), cases caused by subvariant XBB.1.5 accounted for only 0.6% of infections in the week of December 11 in Canada.
L’ASPCargues that the process of identifying strains of infections takes one to three weeks.
Ontario’s COVID-19 genomic surveillance program did not identify the XBB.1.5 subvariant in its latest report. This was based on data collected up to December 10.
