Oh good, I will go and read that shortly. Because this is absolutely one of the main reasons I've been so interested in serological surveys and understanding the true extent of mild or asymptomatic cases of this disease for so long. Its one of the main reasons I have repeatedly said I'm not interested in the current case fatality ratios.
I have still kept going on about the serology (antibody) tests because there are other reasons they are important too. But I probably havent focussed on the potentially game-changing optimistic possibilities for ages because the WHO dampened a lot of hopes on that front with things Bruce Aylward said when their China mission report was released. That was about a month ago now, and although I didnt want to believe its conclusions at the time, I still cannot take those thoughts any further without some kind of data evidence to the contrary of what they said. At the time he said that China did some widespread testing and found very few signs of wider infection rates, but he did also say that they were only just starting actual serology tests there, so he could be back a week later saying something different. Since then I've not heard of any results from China on this, so I remain none the wiser.
One of the reasons I never wanted to rule out much wider spread infection, and the possibility that the impact of this virus is only pronounced and devastating when it first emerges, is that I'm very interested in some of the other coronaviruses that make up a proportion of our seasonal colds. I'm interested in what these viruses would have been like in terms of what impact they would have had when they first arrived in human populations, and how quickly they 'sunk into the background' to the extent that they would be unremarkable and not high on anyones list of priorities.
Anyway I do not like to get my hopes up too much, and in general I find it hard to share optimistic thoughts when especially terrible moments approach. But I can go as far as to say that most of my concerns and tales of horrible woe have been very much focussed on the short term, I would not rule out wonderful outcomes later on, or that some of the huge gaps in our current knowledge are eventually filled with detail that isnt all bad.
