The number of people testing positive for coronavirus in England has jumped 43 per cent, new figures show.

A total of 9,864 new people tested positive in the week to September 2, according to the latest Test and Trace figures.

This is an increase of 43 per cent in positive cases on the previous week, and is the highest weekly number since Test and Trace was launched at the end of May.

In the week ending September 2, some 69.2 per cent of close contacts of people who tested positive in England were reached through the Test and Trace system, according to new figures from the Department of Health and Social Care.

This is down slightly from 69.8 per cent in the previous week, and is the lowest weekly percentage since Test and Trace was launched in May.

For cases handled by local health protection teams, 96.6 per cent of contacts were reached and asked to self-isolate in the week to September 2.

By contrast, for those cases handled either online or by call centres, 61.3 per cent of close contacts were reached and asked to self-isolate.
