The number of cases of COVID-19 sub-variant JN.1 reported from 12 states till January 7 rose to 682, official sources said on Monday.
They said 199 cases have been reported from Karnataka, 148 from Kerala, 139 from Maharashtra, 47 from Goa, 36 from Gujarat, 30 from Andhra Pradesh, 30 from Rajasthan, 26 from Tamil Nadu, 21 from Delhi, three from Odisha, two from Telangana and one from Haryana.
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 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.
States have been urged to ensure effective compliance with the detailed operational guidelines for revised surveillance strategy for COVID-19 shared by the Union Ministry of Health and Family Welfare.
They have asked to monitor and report district-wise cases of influenza-like illness and severe acute respiratory illness in all health facilities regularly for early detection of rising trend of cases.
The 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.
