Following a decision by the HSE yesterday to upgrade restrictions requirements for those entering Ireland from Britain, anyone who arrived here since 8 December is advised to self-isolate for 14 days.
It means those who arrived from 11 December onwards are being asked to eat Christmas dinner alone in their room. The advice has been described by the HSE's Chief Clinical Officer, Dr Colm Henry, as painful but necessary.
Rich Cahill is among those currently self-isolating after returning home from London to see his family in west Cork last week.
Speaking to RTÉ News, Mr Cahill said he restricted his movements for two weeks as a precautionary measure before getting on the plane.
