Funny, I was listening to an interview with an epidemiologist about the Coronavirus lockdown in the States (or at least some of them) and he said it would probably go on for a month, until more information could be found to work out what the risks are and what risk governments and society is willing to tolerate...
...Three months later, the information is still not there.
Another point I would make is that "lockdown" is likely not the only way the spread of the virus can be slowed.
I'd really like to share this interesting article by Erin Bromage about how the virus spreads:

He was on a Podcast "Factually" where he talked some more about lowering the risk when re-opening. Essentially, it boils down to increasing ventilation in buildings, mask wearing in enclosed spaces and being outside as much as possible. In fact, the infectiousness of the virus is estimated to be 18-20x higher inside. He is somewhat against re-opening, but he is acknowledging the reality that it is going to happen.
He has been doing consultation work on re-opening businesses in the US safely and essentially is advising "creative" solutions, like converting car-parks into outdoor dining spaces.
I think we should be following some of this newer science and encouraging businesses to use outdoor space to re-open. Even if it's a tad rainy, the temperatures aren't too bad. And knowing how much lower the risk is, I would feel much safer sitting outside at a restaurant/pub than indoors. I think we should also try and encourage outdoor market style things, fast food restaurants could start serving customers outside, or allow them to pick up at an outdoor counter after placing a mobile order. Let's expand street dining, how about appointments with services like banks taking place outdoors, under marques?
Then we should install large fans and portable ventilation systems to massively increase the turnover of air inside stores and places that have to be inside. In fact, I think this should be done as a priority. Along with aircraft style HEPA filters to constantly clean particles out of the air. Essential stores like supermarkets should probably start to require face coverings, as potentially exposing yourself in these places is non-optional.
So I guess, I'd say that we can re-open, if we are willing to make changes and adaptations which are frankly much less disruptive than a full "lockdown". Considering the US has many more cases than us at the point of their lockdown easing, I think we're in a good state to move forwards with some adaptations.
Have you taken into account the increasing amount of evidence that not all people exposed to the virus produce antibodies, but use other mechanisms of the immune system to fight it off? The proportion who test positive for antibodies are the minimum number of people who have been exposed; the actual number could well be considerably higher.
Yeah, you may be right on that, unfortunately I don't think we have the technology to test that.
Perhaps the only note of caution with that could be whether this weakening is due to warmer weather?
No, definitely not. Perhaps the only thing that could be contributed to warmer weather is the fact that people will be spending less time inside.
The bitter irony being that China looks set to emerge from the whole thing comparatively unscathed, whilst America and Europe burn. One could certainly be forgiven for wondering whether it was deliberate...
Hmm, I think that the situation in Wuhan was much worse than they were letting on. Just look how fast it blew up in Europe and America, then consider that the government wasted time ignoring it. I think, at least in Hubei province, the virus has spread as much as in Italy or the UK at minimum. Fortunately the CCP does not value human life, therefore they will come off relatively unscathed.
