Omicron BA.2 High Mutation
As the Omicron variant is declining and slowing down across the globe. Many countries are removing the restrictions, which was applied back then to stop the spread of infection. But WHO (World Health Organization) has shown a new cause of concern related to the sub-variant of omicron. The Omicron variant has caused a lot of trouble across the globe and led to the third wave of pandemics.
WHO posts a video on Thursday on Twitter, Maria Van Kerkhove, Covid-19 technical lead at WHO said “The virus is evolving and Omicron has several sub-lineages that we are tracking. We have BA.1, BA.1.1, BA.2 and BA.3. It’s really quite incredible how Omicron, the latest variant of concern has overtaken Delta around the world”.
She further added, “Most of the sequences are this sub-lineage BA.1. We are also seeing an increasing in proportion of sequences of BA.2”. The captions of the video on Twitter states that almost 75000 deaths are seen from COVID-19 last week.

BA.2 is more Transmissible Says WHO
In comparison with BA.1, BA.2 is more transmissible according to the evidence.
WHO said, “It is currently unclear what factors drive the growth advantage of BA.2 over BA.1. Preliminary data [from Denmark and the UK] show similar antibody responses to BA.1 and BA.2”.
The official said Omicron is not mild but it is less effective and has less severity than Delta.
Kerkhove said “We are still seeing significant numbers of hospitaliations of Omicron. We are seeing significant numbers of deaths. It is not the common cold, it is not influenza. We just have to be really careful right now”.
According to the reports, BA.2 has a presence in roughly one out of five new cases across the globe.
