Two further cases of the BA.4 Covid variant of concern have been recorded in Ireland.
Fears have risen that the more transmissible strain is now building momentum in the country after two previous cases were reported by Chief Medical Officer Dr Tony Holohan earlier this month.
Although so far, only four cases have been detected, experts believe BA.4 and BA.5 will eventually become the dominant strain in Ireland, with the virus likely to have spread to higher numbers of people already without detection.
