KP.3.1.1, of the Omicron family, is among many currently co-circulating JN.1-derived variants in the US, Xinhua news agency reported.
There is no real need for booster vaccination, said experts even as JN.1, from the lineage of Omicron variant of Covid, is rapidly spreading in the country.
Singapore has reported 1,017 new cases of Covid-19, bringing the total tally to 2,195,980.
Tamil Nadu's health department has said that the state has maximum XBB variants of Omicron and till now no variant of BF 7, which is causing the new wave of Covid-19 in many countries, has been detected in the state.
Stating that at present XBB variant cases are detected in the city, Kejriwal said the Delhi government is doing genome sequencing.
The study by 'bioRxiv', an open-access preprint repository for the biological sciences, shared on Tuesday that its study shows that administration of Covaxin booster dose will enhance the vaccine effectiveness against the Delta variant infection and give protection against the Omicron variants BA.1.1 and BA.2.
Meanwhile, Covid-19 cases have resumed their upward trend, surpassing the 200-mark for the first time since mid-March this week.
"Our analysis suggests that the intrinsic severity of the Omicron variant may be as severe as previous variants," the researchers claimed in the pre-print study, meaning not yet peer-reviewed.
A team of researchers from Universities of Colorado and Northwestern in the US, examined 18,849 children hospitalised with SARS-CoV-2.
The department said that it was expecting the fifth wave of the pandemic by the end of May.
