The Welsh government said it was prepared to “respond rapidly” to the emerging variant, and actions are being taken to slow the spread. The government added there was no substantial evidence the variant would lead to a more severe illness.
“We’re likely to see more cases [of Omicron],” said Dr Eleri Davies, deputy medical director of Public Health Wales (PHW). “There’s no evidence from this first case of any further spread in the community for example, but it is likely that we will see other introductions of this new variant into Wales.” She added: “We are concerned that this new variant does have a significant number of mutations.”
