Earlier today, World Health Organisation Director-General Tedros Adhanom Ghebreyesus said that a new sub-variant BA.2.75 of the Omicron variant of COVID-19 has been detected in various countries including India.
Chief scientist at the World Health Organization (WHO) Soumya Swaminathan, meanwhile, said it was too early to call the sub-variant BA.2.75 more severe.
Besides India, BA.2.75 has also been reported from 10 other countries, Swaminathan said in a Twitter post, adding that and "the WHO is tracking it".
"There's still limited sequencing available to analyse but this subvariant seems to have a few mutations on the receptor binding domain of the spike protein. That's the key part of the virus that attaches itself to the human receptor. So we have to watch that," she said.
"However, it is still too early to known that this sub-variant has properties of immune evasion or being more clinically severe," she added.
