World Health Organisation (WHO) last week pointed out that Omicron is transmitting at a very intense level around the world. “We have sub-lineages of Omicron BA.1 and BA.2.
BA.2 is more transmissible, and this is the most transmissible variant we have seen of the SARS-COV2 virus to date", the WHO official pointed out.
As per the UN Health agency data, in the last 30 days of more than 400,000 sequences sampled, 99.9% are Omicron, and 75% correspond to the BA.2 variant.
Regarding its severity, WHO said, We do not see an increase in severity with BA.2. However, with huge numbers of cases you will see increase hospitalisations and we have seen this in country after country.
