That means 162 new cases were transferred in the latest seven-day period – the largest increase since the regime began.

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 2,481 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 just 66.9 per cent were reached, meaning 822 people were not contacted or did not respond.

That was slightly down from the 67.5 per cent reached up to November 11, but above the 62.3 per cent average across the South East as whole.

Across England, 58.8 per cent 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 November 18.

Local health protection teams deal with cases linked to settings such as hospitals, schools and prisons.

The contact tracing rate including these cases was 60.3 per cent – up slightly from the week before when it was 60.7 per cent.

Around 157,000 new cases were transferred nationally in the week to November 18, the highest weekly number since NHS Test and Trace was launched.
