I really must make progress.
The model estimated the impact of testing and tracing and self-isolation on covid-19 transmission from June 2020 to April 2021. During the period of the study, the model found that testing, tracing and self-isolation had a critical impact on identifying cases of covid-19 and reducing onward transmission. The model found that between 1.2 million and 2 million infections have been directly prevented as a result. Additional assistance is available to those who are being required to self-isolate through the range of financial and practical support measures that the Government have put in place.
I am confident that these two sets of regulations represent proportionate precautionary and targeted action in the face of the new covid-19 variant, the risk of which we still do not yet fully understand. [ Interruption. ]
