A critique of Neil Ferguson’s (the Imperial College) covid19 pandemic model: “much less intrusive, but targeted interventions could have led to similar results to what we are seeing now, with lockdowns”
A few weeks ago our party assembled a team to audit pandemic models that are being used to inform public policy. Team members have a mathematics and programming background, enabling them to examine whether these models’ assumptions are valid.
As part of this independent work, our team has provided input to University College London’s Tim Colbourn on his draft paper on mass-testing in the UK. We also contacted Neil Ferguson of Imperial College and asked him whether he had looked at the option of isolating the elderly as part of his model. I have alluded to his response in an earlier article.
Neil Ferguson has provided his model and source code to a few independent experts. We understand from news reports that he expects to publish it soon on Github, which will enable our team to more thoroughly examine his model.
In the meanwhile, Nirmesh Mehta from our team has made a few observations about the Imperial College model that I believe are wroth sharing at this stage to inform public debate.
Introduction
The 16 March 2020 Imperial College paper, entitled, Impact of non-pharmaceutical interventions (NPIs) to reduce Covid-19 mortality and healthcare demand, has been one of the most influential papers in shaping policy responses to the Covid-19 pandemic. More than 40 days after it was published, we are in a better position to judge the accuracy of its predictions.
