From the Telegraph blog earlier in the day:
New variant is 30 per cent more deadly - Prof Neil Ferguson
The new variant of coronavirus is 30 per cent more deadly than the first version, a top Government adviser has claimed.
Prof Neil Ferguson, who sits on the Government's Nervtag advisory committee, said the latest evidence from university reseachers suggests around 30 per cent more people die of the new variant of Covid - but the data is patchy.
"It is a realistic possibility that the new UK variant increases the risk of death, but there is considerable remaining uncertainty. Four groups - Imperial, LSHTM, PHE and Exeter - have looked at the relationship between people testing positive for the variant vs old strains and the risk of death," he told ITV.
"That suggests a 1.3-fold increased risk of death. So for 60 year-olds, 13 in 1000 might die compared with 10 in 1000 for old strains.
"The big caveat is that we only know which strain people were infected with for about 8 per cent of deaths.
"Only about 25 per cent of people who eventually die from Covid get a pillar 2 test before they are hospitalised (at which point they get a pillar 1 test, but pillar 1 tests don’t tell us which strain they were infected with).
"And we can only distinguish the new variant from the old variant for about 1/3 of pillar 2 tests. All that said, the signal is there and is consistent across different age groups, regions and ethnicities."
