Public health professor and Scottish government advisor @devisridhar lays out what you need for an effective test / trace / isolate programme to stop coronavirus spreading.

So how is England doing?

Not well. https://twitter.com/devisridhar/status/1287477872060489728
Test results given within 24 hours?

87% of Pillar 1 (NHS / PHE) tests
47% of Pillar 2 (private lab) tests

About two thirds of tests overall.
80% of contacts traced?

20% of new cases aren't reached at all, and so can't give any contacts.

20% of the people they DO reach can't or won't give any contacts (or genuinely haven't been in recent contact with anyone else).

22% of the contacts they DO identify aren't reached.
