Two new Covid strains are set to become dominant in Ireland as one top doctor revealed he is worried about people being reinfected.
HSE Chief Clinical Officer Dr Colm Henry said he was concerned about the rising number of people being hospitalised with the virus.
He warned that people could be reinfected with Covid as two sub-variants of Omicron, BA.4 and BA.5 variants, are "becoming more widespread because of their ability to escape immunity".
