The Public Health Agency of Canada is actively monitoring a highly mutated variant of the COVID-19 virus, which has been detected in several countries. However, there have been no cases of this variant reported in Canada thus far, according to Health Canada. The variant, known as BA.2.86, has been classified as a “variant under monitoring” by the World Health Organization due to the significant number of mutations it possesses. While there have been fewer than 10 confirmed cases worldwide as of Friday, health agencies are keeping a close eye on this variant and its associated studies.
The World Health Organization has stated that more data is needed to fully understand BA.2.86, but the presence of numerous mutations is cause for concern. These mutations can potentially make the virus more transmissible and resistant to antibodies produced by vaccines, depending on the evolution of the variant. Countries that have reported cases of BA.2.86 have noted that it is significantly different from its likely parent variants, including the currently dominant XBB.1.5 variant of Omicron.
The U.S. Centers for Disease Control and Prevention has confirmed the presence of this distinct variant in the country. Epidemiologists have identified the initial case in Michigan. However, the risks posed by this variant are still unknown, and further evidence is required to assess its potential impact on public health.
In the United Kingdom, the Health Security Agency has detected one case of BA.2.86 in an individual with no recent travel history, suggesting community transmission within the country. Denmark’s Statens Serum Institut has reported three cases of the variant, which were geographically dispersed and not linked to each other. Experts have noted that the number of mutations present in BA.2.86 is unusual for the virus.
Israel’s health ministry has not provided public information about the new variant, but its detection has been confirmed by various international health agencies. Early analysis suggests that BA.2.86 may have equal or greater ability to evade antibodies compared to the XBB.1.5 variant. However, more sequencing data is needed to fully understand its transmissibility.
In addition to monitoring BA.2.86, Canada is also tracking another notable variant called EG.5. It is important to note that more research is required to fully understand the implications of these new variants.
It is crucial for global health agencies to remain vigilant and continue studying these variants to inform public health measures and vaccine development.
