1. It's just the flu!: The modelling projected that if the UK did nothing, 81% of people would be infected and 510,000 would die from coronavirus by August.
2. Mitigation (some social distancing mainly of the vulnerable): would still result in about 250,000 deaths and completely overwhelm intensive care in the NHS.
3. Suppression (what Wisconsin is doing* plus possible closure to non essential travel): The report concludes "suppression is the only viable strategy at the current time". It is hoped deaths could be limited to the thousands or tens of thousands.
The analysis estimated the limits of intensive care would be "exceeded by at least eight-fold" even under the most optimistic mitigation plans.
As for the "its just the flu crowd".
They said coronavirus was the most serious public health threat seen in a respiratory virus since the 1918 flu pandemic - known as the Spanish flu. The Spanish flu, first diagnosed in Kansas on a military base, is thought to have originated elsewhere. Britain, France and China being the most commonly named.
* Don't know where other states are with this, but Wisconsin has closed all schools and college campuses. Restaurants are doing curbside and takeout only, bars malls and churches are closed and gatherings are limited to 10 people.
