The first cases of the new sub-variant of Omicron have been detected in Wales.
Omicron BA.2 - which has been called the 'stealth variant' by scientists due to it being harder to detect - has spread rapidly across several countries, with hundreds of cases detected in England last week.
Public Health Wales has confirmed that "small numbers" of the Covid variant have now been found in Wales, while the UK Health Security Agency (UKHSA) has declared it a 'variant under investigation' with experts closely monitoring its growth, North Wales Live reports.
