Test and Trace is still missing four in ten close contacts as number of people notified continues to fall since its launch in May
由于自5月份推出以来，被通知的人数持续下降，Test and Trace仍有十分之四的亲密联系人失踪。
About four in ten contacts of those testing positive for Covid-19 are still not being reached through the Test and Trace system.
Some 60.5 per cent of close contacts of people who tested positive in England were told to isolate in the week ending November 11, according to the Department of Health and Social Care.
英国卫生与社会保障部(Department Of Health And Social Care)的数据显示，在截至11月11日的一周内，英国约60.5%的密切接触者被告知隔离。
It is the fifth week in a row that the figure has been just above 60 per cent.
The proportion of contacts reached has fallen gradually since Test and Trace was launched at the end of May, when the figure stood at 91.1 per cent.
自5月底推出Test and Trace以来，接触者的比例逐渐下降，当时这一数字为91.1%。
For cases managed by local health protection teams, 98.9 per cent of contacts were reached and asked to self-isolate in the week to November 11.
For cases managed either online or by call centres, 58.9 per cent of close contacts were reached.
Downing Street defended the 'colossal' achievements of Test and Trace but acknowledged improvements could be made.
A No 10 spokesman added: 'We are testing more people per head of population than any other European country and that will grow thanks to our increased testing capacity.'
Of the 156,853 people transferred to the system in the week to November 11, 84.9 per cent were reached and asked to provide details of close contacts.
