Dismissing as preposterous" a Republican senator's claim he is overhyping" Covid-19 as he did HIV and Aids, Dr Anthony Fauci said on Sunday the threat to the US from the Omicron variant remained to be determined - but that signs from South Africa, where the variant emerged, were encouraging.

Clearly in South Africa Omicron has a transmission advantage," Fauci told CNN's State of the Union, because ... they were very much at a low level then they had almost a vertical spike upwards, which is almost exclusively Omicron.
