India reported its first two cases of the Omicron variant of COVID-19 on Thursday from Karnataka – in a South African national and a Bengaluru doctor with no travel history and both men fully vaccinated.
The official said the new strain is still under study, and it will take at least two weeks to ascertain its nature.
The Omicron variant is believed to be more infectious than the Delta variant, as it has a significantly high number of mutations and spike protein, he added.
Mizoram reported 275 fresh COVID-19 cases on Thursday, taking the state's tally to 1,35,450. The death toll rose to 501 with one more fatality.
