1. Cases

1a. Pillars 1&2 - last couple of weeks & last month (current wave) & full curve. Bear in mind the left-hand side was heavily rationed for testing, the right-hand side far less so: the 'two waves' are not comparable.

1. Cases

1b. English pillar 1 (clinical need / NHS) and pillar 2 (community swab) cases and % positive. The left-hand side was heavily rationed for testing, the right-hand side *far* less so.

2. Care home outbreaks

*Critical data*. In week 38 there were 134 acute respiratory incidents with at least 1 +ve covid test.

3. Hospital deaths and admissions

Covid deaths from NHS England stats (2nd wave now visible): https://england.nhs.uk/statistics/statistical-work-areas/covid-19-daily-deaths/

Covid admissions (total & recent) & covid patients on ventilators (predictor of deaths): https://coronavirus.data.gov.uk/healthcare?areaType=nation&areaName=England
3b. An aside on admissions

Covid admissions are still growing at a linear, rather than exponential, rate. *This could change*.
4. Triage

111 covid triage should be an excellent lead indicator of hospital admissions, *particularly* for the aged 70+

Thrown off recently by school / college kids seeking tests, but now falling back. No sharp increase in the vulnerable 70+.

5. Incidence (ONS)

17 day doubling, faster in the young.

We want *more* contrast between incidence in the old versus young, current policy holds that back: the sooner it passes through the young, the sooner it passes over the elderly / vulnerable.

6. Contact tracing

Each isolation via contact tracing has cost £300k, and most of these are our own housemates and guests whom we could have told anyway.

7. The Vallance-tracker

At Monday's presser @uksciencechief and @CMO_England presented only one scenario for the progression of UK cases (by report date), to 50,000 per day by mid-Oct; so it seems right to hold them to account on this until any alternative is presented.
8. Mortality

This will be an interesting one to watch for the rest of the year, if covid has taken a lot of people who might otherwise not have survived Nov/Dec flu season.

Note 2014/15 and '19: a light mortality year creates "dry tinder".
