Covid cases are on the rise in the UK, and another sub-variant of Omicron has been detected since being identified in India.
'Centaurus' is the latest sub-variant identified and cases have so far been found in Britain, the US, Germany, Canada, Australia and other countries.
Also known as Omicron variant BA.2.75, it is closely related to the BA.5 and BA.2 variants but may spread even faster than its cousins.
