Contact tracers ask new patients to give details for anyone they were in close contact with in the 48 hours before their symptoms started.
This led to 17,737 close contacts being identified over the period – those not managed by local health protection teams, which are dealt with through a call centre or online.
But 84% of those were reached, meaning 2,833 people were not contacted or did not respond.
That was up from the 82.4% reached in the period to January 6
Across England, 92.8% of contacts not managed by local health protection teams were reached and told to self-isolate by NHS Test and Trace in the latest week to January 13.

Around 352,000 new cases were transferred nationally in the week to January 13.
