A new Covid variant labelled the "most transmissible yet" has been sweeping across the country.
Named XBB.1.5, this variant is a relative of the notorious Omicron, evolving from the XBB variant that arrived in Ireland last year, the Irish Independent reported.
Having first been detected in January, it has been the predominant variant found in patients in Ireland with sever acute respiratory infection, with the World Health Organisation saying it has a large growth advantage over others.
