@PatriciaHolm thanks for the clarity on the 75.000 and 44,000 numbers.
Is the 75.000 just for the designated London boroughs? Or does it include the bits of Essex and Kent as well? The wording seems to imply the former in the govt statement, although no numbers specified for Essex and Kent.
The London part referenced staff, students and their families.
The last ONS mid year estimate has 168,000 11 to 17 yr olds (eg 7 year groups) or 165000 12 to 18 year olds for those 7 London boroughs - city of London not included, that would add another 500 to either group. Uplift for parents and staff and we are in the region of 450,000 to 500,000 people.
For context London overall had around 180,000 p2 tests (PCR and LF) in the last full 7 days. So an extra 75,000 for seven boroughs is a good short-term uplift.
Uptake will of course be key.
