A new subvariant of Omicron has been detected in Ireland - with a Danish study suggesting it's even more transmissible than the original.
The latest Health Protection Surveillance Centre (HSPC) report has confirmed the existence of the BA.2 subvariant in Ireland.
BA.2 - also known as "stealth Omicron" - was first detected earlier in 2022 and has now become the dominant variant in Denmark.
