VOC1 now clearly the endemic strain UK Almost 
of cases in London and South East are VOC1

65 deaths among wild type cases vs 104 in UK variant cases
Mortality risk ratio of 1.65 (1.21-2.25)
65 deaths among wild type cases vs 104 in UK variant cases Mortality risk ratio of 1.65 (1.21-2.25)
Updated secondary attack rate analysis NHS T&T data.
Yet more evidence of
transmissibility.
~3 MILLION contacts analysed 
25-40% attack rate in SGTF cohort (866k contacts) (all ages, all regions)
Huge numbers narrowing that point estimate to ~1/3 more infectious.

11-55% attack rate in genomic cohort (37k contacts) Smaller numbers, wider range but still mid-point around 1/3 more infectious
