Chief Medical Officer Dr Tony Holohan said: "The number of hospitalisations are increasing faster than the exponential growth modelling predicted.
"This indicates a rapidly deteriorating disease trajectory nationally."

HSE chief executive Paul Reid today said hospitals are coping for now, but added that officials are very concerned about the situation as we head into the winter months.
