At some point we need to start looking at the economic fallout, and also whether the curtailed freedoms will be returned, or if the world will live in a locked down police state for ever.
Indeed, and that will be the really hard question!
I read in today's Sunday Times (not a very reliable source, but this piece looks like straight reporting) that in China the restrictions around Wuhan have just been lifted. The outcome of that would tell us a lot if the Chines could be relied on to publish reliable information (the same article says that the number of cremation urns delivered to Wuhan is reputed - unconfirmed of course - to be around twice the reported number of deaths!).
Italy might also be helpful because it is a couple of weeks ahead of us.
The big experiment is in the US, where Donald Trump has just decided not to imposed a lockdown in New York. If disaster doesn't happen there (but I very much fear it will) the world will relax somewhat.
Here are some things which I think all the scientists would agree on:
1. The virus will continue to spread throughout the population - how fast depends on how much people mingle.
2. This will continue until we reach herd immunity (around 60% infected and recovered) or until a vaccine is developed (around 12 months away, with luck).
3. The death rate is about twice that from seasonal flu if hospitals are not overwhelmed, so there will be accelerated deaths and a number (unknown) of additional deaths above normal rates.
4. If hospitals are overwhelmed, the death rate increases by a multiple of 5-10.
5. There might be some antivirals available in the early Autumn which will reduce death rates back to something like normal seasonal flu (though there will be more cases because the virus spreads more easily).
The political decisions will be about how to react to these. How long can restrictions be maintained without the population revoting? (This will vary among societies). How much damage to the economy is sustainable without other effects occurring which have even worse consequences? (No idea!)
As part of the mix there will normal, self-serving political questions such as: Will I be blamed and thus not re-elected.
Like anything complicated, there are no easy and obvious answers, and a range of answers to choose from. Because predicting the future is difficult, choosing between them is also difficult.
