Public health officials are monitoring whether several counties need to have level 3 restrictions imposed, like Dublin.
Meanwhile, 47% of the Irish population think the worst of the Covid-19 pandemic is ahead of us.

The survey also found that 52% of the population are in favour of more restrictions being introduced.
