The Deputy Chief Medical Officer says they're concerned about the increased transmissibility of the Delta variant.
But Dr Ronan Glynn says the measures for coping with the virus remain the same:
"Avoid crowds, and don't meet up in large groups. Meet people outside where possible and if meeting inside, make sure that windows are open and that the room is well ventilated. Wear a mask and wash your hands or use hand sanitizer regularly. And above all, if you've any cold or flu-like symptoms, then assume that it has COVID, isolate and get a test."
