Delta Plus: the Liverpool region with the highest proportion of new COVID-19 mutation

Lab tests on more than 26,000 recent Covid-19 samples reveal the areas of England where the new Delta Plus mutation is spreading.

A mutated form of COVID-19 may now account for up to two in five cases in parts of England, research shows.

Officials designated the strain AY.4.2, nicknamed Delta Plus, a “variant under investigation” on October 20.

Scientists have said it may spread more easily than the standard Delta strain, but there is no evidence that it cause more serious illness.

There is also no evidence that the three coronavirus vaccines used in the UK - Pfizer-BioNTech, Moderna and AstraZeneca - are any less effective against the new strain.

Preliminary findings from the Wellcome Sanger Institute, one of the research bodies that works with the UK Health Security Agency (UKHSA), show potential hotspots.
