SARS-CoV-2 variants of concern

Viruses constantly change through mutation and many variants of the SARS-CoV-2 virus have been observed worldwide. Not all mutations have a significant impact on the spread of the virus, but some can provide the virus with selective advantages, such as increased transmissibility or the ability to evade immune responses.

Due to changes in the proportion of cases with Variants of Concern in Ireland, guidance relating to contact tracing is currently being reviewed and will be updated in due course.
