Yes, we hope very much to be able to publish more and more granular, localised information and to work with local leaders to deliver on what is needed to act upon it.
John Redwood (Wokingham) (Con)
Given the Secretary of State’s great success in expanding the number of tests, will we soon have more precise and accurate R figures, along with the other information now accumulated, and is there not a danger, in interpreting back trends, that they are unreliable because of differential test rates?
Matt Hancock
The answer is yes and yes. Survey testing is the most reliable way of assessing the prevalence of the disease and its downward trajectory, because it takes into account a randomised approach to working out where the disease is—much like the opinion polls that we are familiar with in this House—because as testing has gone up, inevitably more cases have been found. It is a good thing that more cases have been found, but we need to know the prevalence, which is best done by surveys.
