At the press briefing this evening, Dr Ronan Glynn Acting Chief Medical Officer at the Department of Health said that the National Public Health Emergency Team (NPHET) is particularly concerned by the growing number of Covid cases in Dublin and Limerick.
"We are monitoring with growing concern the number of cases nationally, particularly in Limerick and Dublin.
"The next seven days are vital; everyone needs to reduce their contacts and assume any person you do meet may be carrying the virus," he said.
He said there is a need for a "higher level of risk perception".
"We really need people to pay attention to the basic messages," he said.
Dr Glynn also encouraged people who may be experiencing Covid-19 symptoms to contact their GP immediately.
"People have a natural tendency to wait and see but you need to put your hand up sooner if you are experiencing any symptoms," he said.
Professor Pete Lunn, founder and head of the ESRI’s Behavioural Research Unit said "now is the time to plan for the winter months ahead."
"Take control of your own environment by ensuring your household is up to date on, and actioning, the public health advice.
"Make it a habit to get outside, to socialise and exercise safely and automatically physically distance from others. "Adapt to Covid-responsible behaviours in and out of the home.
"Plan for the milestones; such as Halloween, Christmas and New Years Eve within a Covid-19 environment.
"Be innovative in how you can celebrate safely with loved ones," he said.
"This year will bring added challenges so prioritise your mental and physical health, know how you will invest in them each week.
"Choose your close network of social visitors this winter and prioritise members of your family or friends who may be more isolated," Professor Lunn continued.
So far there have been 1,777 Covid-19 related deaths in Ireland.
