Omicron subtype XE, first identified in the UK in January, is what experts call a “recombinant virus”. A recombinant virus is a combination of genetic material from two or more different viruses – in this case, the original Omicron subtype (BA.1) and the more contagious BA.2.

As of April 6, Canada had identified six cases of recombinant XE genealogy, the Public Health Service of Canada (PHAC) told Global News on Wednesday. “Once you have everything open now – without a mask and nothing – the possibility of creating new mutants, variants or new recombinations is always open,” said Dr Horacio Bach, an infectious disease specialist at the University of British Columbia. The story goes on under the ad XE is classified in the Omicron concern variant, and the World Health Organization (WHO) says it will fall into that lineage until any significant differences in transmission and severity are reported. Here’s what we know so far about the recombinant XE variant of Omicron.
What is a recombinant variant?
All viruses mutate and have subtypes that have a different genetic composition from the original variant but have a common origin. The story goes on under the ad A recombinant variant is created when two variants infect the same cell in the body at the same time, Bach said.

“Recombinant variants are not uncommon, especially when there are many variants on the market, and several have been identified during the pandemic to date,” said Susan Hopkins, UKHSA Chief Medical Adviser, in a statement on March 25. . “As with other types of camouflage, most will die relatively quickly,” he added. XE is a combination primarily of BA.2 spike protein – which is responsible for entering cells – but it also has BA.1 genes, said Canada’s public health chief Dr. Theresa Tam during a press conference on Tuesday. 2:14 Where have the older variants of anxiety gone? Where have the previous variants of concern gone? – 24 February 2022 Based on early analysis, XE is about 10 percent more contagious than BA.2, according to the WHO. Trending Stories

UKHSA said XE has been identified as the basis for Community transmission and potential growth in the UK. The agency estimates a growth rate of 12.6 percent above that of BA.2, which is leading the sixth wave of COVID-19 in Canada. However, the WHO, PHAC and UKHSA say more data is needed to confirm increased transmissibility. 1:49 Concerns over COVID-19 re-infection rise as Canada faces Wave 6 Concerns over COVID-19 re-infection rise as Canada battles Wave 6 Although only six cases have been reported in Canada, Bach estimates that, due to a lack of testing, this number is likely to be much higher. The story goes on under the ad A higher level of transmission means that there will be more virus in the environment and more people can be infected, he explained.
Severity, vaccine effectiveness
So far, there is not enough evidence to draw conclusions about whether XE can cause more serious illness or affect the effectiveness of the vaccine, experts say. The PHAC said scientists were looking for evidence that XE alters disease severity, transmissibility or affects the effectiveness of diagnostic tests, vaccines or treatments for COVID-19. “Right now, it does not seem to be serious or more serious compared to the other (BA.2),” Bach said.
