The imperial college study is really interesting. I am not an epidemiologist, but it's a bit weird they rely on some of the italian numbers for some of their parameters. Anyways, that probably just inflates some numbers somewhat. What's more interesting is that they conclude:
" The major challenge of suppression is that this type of intensive intervention package –
or something equivalently effective at reducing transmission – will need to be maintained until a
vaccine becomes available (potentially 18 months or more) – given that we predict that transmission
will quickly rebound if interventions are relaxed."
Now, there is no single definition of social distancing. But if we look at for instance Denmark and Norway, that means no travel (airline or otherwise), pubs, bars, restaurants, football or (any sports), going to the gym, hotels, concerts, festivals, conferences, movies or cinemas, theatres, summer house or cabin etc etc for 18 months. That's crazy. Will there even be an Arsenal on the other side if suppression lasts for 18 months?
