The Centre on Friday told the states and Union territories that currently the World Health Organisation is closely tracking one variant of interest (VOI), XBB.1.5 and six other variants are under monitoring BQ.1, BA.2.75, CH.1.1, XBB, XBF and XBB.1.16.
During a review meeting on the Covid-19 situation, Union Health Minister Mansukh Mandaviya virtually interacted with the health ministers of the states and union territories and advised them to ramp up vaccination of all eligible population, especially of the elderly and vulnerable population group.
It was highlighted that while Omicron and its sub-lineages continue to be the predominant variant, most of the assigned variants have little or no significant transmissibility, disease severity or immune escape.
The prevalence of XBB.1.16 increased from 21.6 per cent in February to 35.8 per cent in March, 2023. However, no evidence of an increase in hospitalisation or mortality has been reported. It was also informed that while India has achieved over 90 per cent coverage of primary vaccination, the coverage of precaution dose is very low.
