Covid-19 variant Omicron and its sub-lineages continue to be the dominant variant in India with ‘XBB’
being the most prevalent sub-lineage circulating all over the country.
Four cases of new Omicron subvariant XBB.1 and one case of XBB, have been diagnosed in Madhya Pradesh, according to INSACOG.
XBBXBB is a recombinant of BA.2.10.1 and BA.2.75 sublineages. … BQ.1* has a prevalence of 6% and it has been detected in 65 countries.
XBB.1.5 is a new recombinant strain and is both more immune-evasive and better at infecting than BQ.1 and XBB, the virologist said adding that it is not a ‘typical Omircon’,

Scientists at Columbia University have warned that the rise of subvariants such as XBB could “further compromise the efficacy of current Covid vaccines
And result in a surge of breakthrough infections as well as re-infections.”
The current spike in COVID cases in China is believed to be caused by the BF.7 sub-variant of Omicron.
XBB was first identified in India in August. It quickly becomes dominant there, as well as in Singapore.
It has since evolved into a family of subvariants including XBB.1 and XBB.1.5.
On the bulletin of December 5 which was also released on Monday, the INSACOG said overall the infection rate is below 500 per day.
