COVID-19: 51 cases of Omicron's “little brother” detected in the country

COVID-19: 51 case of “little brother” of Omicron d” protected in the country


Federal Public Health has confirmed 51 cases of the Omicron subvariant in the country, cases believed to be “primarily from international travellers.” 

< p>The BA.2 sub-variant is known in France as the “little brother” of the Omicron variant, whose scientific name is BA.1. It differs in a few ways from Omicron, most notably in its spicule, which covers the outer membrane of the virus.

Little is yet known about this subvariant, but gradually preliminary studies tend to demonstrate that it is not more virulent than the previous variants, although it could prove to be even more contagious than its “big brother”.

“At present, there is very limited evidence to determine the impact of the differences between BA.1 and BA.2, hence the continued efforts of [Public Health Agency of Canada] scientists (PHAC) to monitor cases here in Canada and follow the evolution of the situation internationally,” explains Anne Génier, spokesperson for Health Canada.

The distribution of these cases in the country remains unknown at this time. The National Institute of Public Health of Quebec (INSPQ) did not immediately respond to our request on Wednesday.

It's especially Denmark where it is noted that it took the lion's share in the epidemiological portrait.

The Nordic country of 5.8 million inhabitants recorded 46,000 new cases on Tuesday alone.

Despite a dizzying increase in cases of contamination, the Danish government intends to move forward with its deconfinement plan as of February 1, given the high rate of vaccination and the lesser severity of infections.

The Danish Minister of Health has indicated “that the categorization of Covid-19 as a disease threatening to society [will] be abolished from February 1, 2022”.

Almost 60% of the 5.8 million Danes received a booster dose, one month ahead of the schedule envisaged by the health authorities.

Note that the high proportion of cases of the BA.2 variant could also be due to the Danish screening system, which places more emphasis on screening than other countries.

The World Health Organization Health (WHO) still called on countries to keep an eye on the sub-variant because of its high contagiousness. The UN agency is asking countries to investigate the variant to be certain of its potential.

The subvariant is making its way to countries on all continents, but its presence is most noticeable in Denmark, India and the UK so far.
