Over the past 24 hours 14 people have been admitted to Irish hospitals with covid-19.
It's the highest number of new virus-related admissions recorded since May.
The National Public Health Emergency Team is closely monitoring the situation in 8 counties.
Louth, Waterford, Limerick, Kildare, Leitrim, Donegal, Offaly and Wickow are displaying worrying trends.
The HSE's Chief Clinical Officer Colm Henry believes restrictions need to remain in place until a vaccine is developed:
“The figures are going up in those countries and the same rules apply in that there is no cure for this virus; there is no safe effective, widespread vaccine available.
“In that context, the only way we can prevent uncontrolled transmission, which is the greatest threat to our population, is restricting social contacts.
“Reducing the number of settings where the virus can jump from household to household and individual to individual.”
