COVID-19 sub-variant JN.1 has spread to 15 states and Union territories with a total of 923 cases of the infection reported so far, according to the Indian SARS-CoV-2 Genomics Consortium (INSACOG).
Data compiled by the INSACOG showed Karnataka has reported the highest number of cases at 214, followed by Maharashtra (170), Kerala (154), Andhra Pradesh (105), Gujarat (76) and Goa (66).
Telangana and Rajasthan have recorded 32 JN.1 cases each, Chhattisgarh has recorded 25, Tamil Nadu 22, Delhi 16, Haryana five, Odisha three, West Bengal two and Uttarakhand one.
Even though the number of cases is rising and the JN.1 sub-variant has been detected in the country, there is no cause of immediate concern as the majority of those infected are opting for home-based treatment, indicating a mild illness, officials said.
The Centre has asked the states and Union territories to maintain a constant vigil amid an uptick in the number of Covid cases and the detection of the JN.1 sub-variant in the country.
The states have been urged to ensure effective compliance of the detailed operational guidelines for the revised surveillance strategy for COVID-19 shared with them by the Union Ministry of Health and Family Welfare.
The states have also been asked to regularly monitor and report district-wise cases of Influenza-like Illness (ILI) and Severe Acute Respiratory Illness (SARI) from all health facilities for an early detection of a rising trend of cases.
The World Health Organisation (WHO) has classified JN.1 as a separate 'variant of interest' given its rapidly-increasing spread, but said it poses a 'low' global public health risk.
The JN.1 sub-variant of the coronavirus was previously classified as a variant of interest (VOI) as part of the BA.2.86 sub-lineages, the parent lineage that is classified as a VOI, the world body said.
