A public health expert says other viruses have not changed substantially in severity.

DCU Professor of Health Systems Anthony Staines says Omicron has caused less havoc as we're vaccinated, but it doesn't stop it.

He says it seems to be the nature of this group of viruses that they don't generate long-term immunity.

10,753 new PCR cases of covid 19 have been confirmed and 4,208 positive antigen tests have been logged through the HSE portal.

Professor Staines says other viruses remained severe as could be the case with covid 19
