A newly detected coronavirus variant is on the rise in England, with the virus believed to be an offshoot of Delta.
According to a briefing from the UK Health Security Agency, released on Friday, “a Delta sublineage newly designated as AY.4.2 is noted to be expanding in England”, with the body adding that the variant is being monitored and assessed.
The report states that in the week beginning 27 September – the last week for which complete sequencing data was available – AY.4.2 accounted for about 6% of sequenced coronavirus cases and is “on an increasing trajectory”.
AY.4.2 contains two mutations in its spike protein, called A222V and Y145H. The spike protein sits on the outside of the coronavirus and helps the virus to enter cells.
