To ask the Secretary of State for Health and Social Care, how many people contacted through the NHS Test and Trace service have been asked to self-isolate to a date that has already passed from the date on which they were contacted through that service.

As of 20 January 2021, 95.3% of people who tested positive for COVID-19 and were reached by the service were contacted within 72 hours of their case being transferred to the contact tracing system.

For the same period, 99.4% of people identified as recent close contacts of positive cases who were reached by the service were contacted within 72 hours of the case being transferred to the contact tracing system.
