Pune (TIP)- Chief scientist at the World Health Organization (WHO), Dr Soumya Swaminathan, on Thursday said some countries may see “another wave of infections” with the XBB subvariant of Omicron, a variant of COVID-19 virus. Talking to reporters on the sidelines of the annual general meeting of the Developing Countries Vaccine Manufacturers Network (DCVMN) here, she clarified that as of now, there was no data from any country to suggest that these new variants are clinically more severe.
“There are over 300 subvariants of Omicron. I think the one that is concerning right now is XBB, which is a recombinant virus. We had seen some recombinant viruses earlier. It is very immune-evasive, which means it can overcome the antibodies. So slightly that we may see another wave of infections in some countries because of XBB,” she said.
Swaminathan said they are also tracking derivatives of BA.5 and BA.1, which are also more transmissible and immune-evasive.
As the virus evolves, it is going to evolve more and more transmissible, she said.
“As of now, there is no data from any country to suggest these new subvariants are more clinically severe,” she clarified.
Suggesting the measures that need to be taken, Dr Swaminathan said monitoring and tracking are the key steps. Source: PTI
