INSACOG experts are conducting genomic analysis of a coronavirus case reported as that of the highly transmissible XE variant by Mumbai civic officials, though scientific evidence so far does not indicate it to be so, official sources said on Wednesday.

The Brihanmumbai Municipal Corporation (BMC) on Wednesday said that a woman who had arrived there from South Africa in February-end and tested positive for Covid-19 on March was infected with the XE variant, which was first detected in the UK.
