A new Covid sub-variant may soon outpace Omicron after more than 400 cases were found in the UK, scientists believe.
The variant, nicknamed 'Stealth Omicron' and known to scientists as BA.2, is now said to be responsible for over 8,000 cases worldwide.
Designated a 'variant under investigation' by the UK Health Security Agency last week, it is believed that Stealth could be more transmissible with a better chance of evading current vaccines.
