JN.1 Variant: The Covid-19 subvariant JN.1 has been detected in a number of elements of Kerala, surveillance performed by the Indian SARS-CoV-2 Genomics Consortium (INSACOG), a multi-laboratory community that displays genomic variations in novel coronavirus, has revealed. JN.1 is a mutation of the Omicron subvariant BA.2.86, and was first detected in the USA in September 2023. Within the US, JN.1 accounted for 21.4 per cent of circumstances as of December 12, 2023.
