Coronavirus: Disease Control

Question for Department of Health and Social Care

UIN HL11369, tabled on 10 December 2020

To ask Her Majesty's Government, further to the remarks by Lord Bethell on 1 December (HL Deb, cols 717–21), what assessment they have made of the efficacy of lockdowns in preventing the transmission of COVID-19.

Evidence suggests that more stringent interventions tend to reduce the reproduction number of the virus.

The lockdown imposed in late March and the changes in behaviour that preceded this had a high level of uptake and resulted in a rapid reduction in the reproduction number ‘R’ from about 2.5-3.0 to about 0.5-0.7. That is a reduction in ‘R’ of about 2, or a reduction in transmission of 75%. We continue to review the efficacy of measures.
