Sanger removes cases from travellers to England & from surge testing to get a picture of what is happening in the community.
In England, within TWO weeks to 1 May, B.1.617.2 (the new variant of concern) went from 1% to 11% of cases. Other variants <1%.
A massive increase. 2/6
This is concentrated in a few regions: London, the NW (quickest rise), East of England and then E Midlands & SE.
PHE also highlighted London and NW as particularly concerning in its Friday report

In the NW cases are concentrated in a few towns with v high proportion B.1.617 w/e 1 May: highest are Blackburn with Darwen (75%), Bedford (73%), Bolton (69%).
These are obv low numbers of cases. But what is happening to overall covid cases here? 4/6
Downloading data from coronavirus.data.gov.uk/details/downlo… for each local authority shows that, compared to week before, cases in week to 5th May have increased by 43% (Blackburn), 58% (Bedford) and 91% (Bolton).
It's not more tests - tests look flat & all 3 have growing PCR positivity. 5/6
UKHSA data dashboardOverall summary of the respiratory viruses in circulation within the UKhttps://coronavirus.data.gov.uk/details/download
Under *current* restrictions, within a context of v infectious B117 ("Kent" variant) and *high population immunity* B.1.617.2 seems to be spreading quickly.
Numbers still low(ish) but for how much longer? What will happen after 17th May when so much more opens? 6/6
PS this is not about returning to lockdown, it's about taking this seriously & strengthening public health measure such as contact tracing, support for isolation, testing, masks in indoor spaces (inc schools). it's about getting on top of situation *now*
