UK says it is monitoring subvariant of COVID Delta strain

Britain says it is monitoring a subvariant of the Delta strain of the coronavirus, which has been seen in a growing number of cases.

Prime Minister Boris Johnson’s spokesman says the government is keeping a “close eye” on the AY.4.2 variant, but says there is no evidence it spreads more easily.

“As you would expect, we are monitoring it closely and won’t hesitate to take action if necessary,” he tells reporters.

Overall infection rates in Britain remain stubbornly high, despite high rates of vaccination, and on Monday nearly 50,000 new cases of COVID-19 were recorded.
