Here’s an article about it:
The new forecasts, by Neil Ferguson and his colleagues at the Imperial College COVID-19 Response Team, were quickly endorsed by Johnson’s government to design new and more extreme measures to suppress the spread of the virus.
The report is also influencing planning by the Trump administration. Deborah Birx, who serves as the coordinator of the White House coronavirus task force, cited the British analysis at a news conference Monday, saying her response team was especially focused on the report’s conclusion that an entire household should self-quarantine for 14 days if one of its members is stricken by the virus.

…Perhaps our most significant conclusion is that mitigation is unlikely to be feasible without emergency surge capacity limits of the UK and US healthcare systems being exceeded many times over. In the most effective mitigation strategy examined, which leads to a single, relatively short epidemic (case isolation, household quarantine and social distancing of the elderly), the surge limits for both general ward and ICU beds would be exceeded by at least 8-fold under the more optimistic scenario for critical care requirements that we examined. In addition, even if all patients were able to be treated, we predict there would still be in the order of 250,000 deaths in GB, and 1.1-1.2 million in the US.
In the UK, this conclusion has only been reached in the last few days, with the refinement of estimates of likely ICU demand due to COVID-19 based on experience in Italy and the UK (previous planning estimates assumed half the demand now estimated) and with the NHS providing increasing certainty around the limits of hospital surge capacity.
We therefore conclude that epidemic suppression is the only viable strategy at the current time. The social and economic effects of the measures which are needed to achieve this policy goal will be profound. Many countries have adopted such measures already, but even those countries at an earlier stage of their epidemic (such as the UK) will need to do so imminently.
Our analysis informs the evaluation of both the nature of the measures required to suppress COVID19 and the likely duration that these measures will need to be in place. Results in this paper have informed policymaking in the UK and other countries in the last weeks. However, we emphasise that is not at all certain that suppression will succeed long term; no public health intervention with such disruptive effects on society has been previously attempted for such a long duration of time. How populations and societies will respond remains unclear. (Impact of non-pharmaceutical interventions (NPIs) to reduce COVID19 mortality and healthcare demand)
