Covid cases are once again on the rise in Ireland, with 574 people now in hospital with the virus, 23 of whom are being treated in ICU.
The surge has caused many to question whether or not restrictions such as mask-wearing should be reintroduced. And if they were brought back in, would they make a difference?
Speaking on Newstalk Breakfast, Professor of Immunovirology at UCC Liam Fanning said he does not see a need for the reintroduction of masks given the current situation.
