WHO: New Omicron Subvariant XBB.1.16 Is ‘One to Watch’

The World Well being Group on Wednesday mentioned that it’s monitoring XBB.1.16, an omicron subvariant that has been documented principally in India.

“We’re monitoring it as a result of it has potential modifications that we have to maintain a superb eye out on,” Maria Van Kerkhove, WHO’s COVID-19 technical lead, mentioned at a press convention.

The pressure has been reported in 22 nations, with the vast majority of instances coming from India.

“In India, XBB.1.16 has changed the opposite variants which can be in circulation,” Van Kerkhove mentioned. “So that is one to look at.”

India is seeing a rise in coronavirus instances. In line with WHO, India is experiencing the very best proportional improve in infections of its area, reporting over 10,500 new instances over the previous 4 weeks in comparison with practically 3,000 infections in the course of the earlier 4 weeks.

The subvariant has been circulating for a number of months, Van Kerkhove mentioned, noting that it doesn’t seem to trigger extra extreme illness.

“We’ve not seen a change in severity in people or in populations, however that is why we’ve got these programs in place,” she mentioned. “Techniques to trace the virus variants, world collaborations to evaluate transmissibility, immune escape, severity and the affect of any of our interventions together with diagnostics, therapeutics and vaccines.”

In line with Van Kerkhove, the pressure is just like XBB.1.5, which is dominant within the U.S.

“It has one further mutation within the spike protein, which in lab research reveals elevated infectivity in addition to potential elevated pathogenicity,” Van Kerkhove mentioned.

XBB.1.16 has been documented within the U.S. however doesn’t but seem on the Facilities for Illness Management and Prevention’s variant tracker.

The subvariant is only one of greater than 600 omicron subvariants that WHO is monitoring.

“One of many issues we’re very involved about is the potential for the virus to alter to grow to be not solely extra transmissible however extra extreme,” Van Kerkhove mentioned. “So we’ve got to stay vigilant.”
