But isn't there a lag? I really struggle to see how significantly controlling people's movements for a month isn't going to have a major effect.
I don't think the goal needs to be, or should be, to get cases down to very low levels. You just want a rate the hospitals can cope with and that people can bear risk with as they see fit. I think that's the sensible compromise if we assume some kind of vaccine will be available in the next 6 months. Whatever achieves that - maybe something like a month of normal distancing followed by a couple of weeks of lockdown.
I can only go on the Melbourne experience.
Yes - there is a lag - so what you do today, you start to see the effects in 2 weeks.
Melbourne lockdown started to see figures come down after about 4 weeks - after about 6 weeks it started to get to similar figures for when it started. After another 4 weeks, then the number gets down to a really low level - then a few weeks of consistently low and we started to open up.
If you open too early - then I guess you’d expect to see cases go up and hasten another potential lockdown scenario.
If you can get the cases down low - so that it is manageable at a local level, then you can open up “more”.
I’ve got to say - there’s no more than 20 people allowed in a pub/restaurant, but they along with more retail outlets are now open.
Melbourne Cup today - no spectators.
State borders are still closed - still not supposed to more the 25kms - but it’s obviously better than before.
That initial lockdown period was were we we had a 9pm-5am curfew, not allowed out for more than an hour - you had to get paperwork to prove you were an “essential” worker - only one person per household, per day to do essential shopping, no more than 5kms away.
Also remember, the numbers at our peak were lower than the numbers you’re seeing in the UK before lockdown was even considered.
I don’t think like-for-like is entirely useful - because it’s much easier to lockdown 5 million people in Melbourne than any sort of way a UK lockdown could work - but on the other hand it does offer a possible solution.
I can’t see how the UK gets this down enough to only run a 4 week lockdown.
