Tick tock.
I wonder if testing can establish if someone has had the virus and recovered from it.
When testing wider populations, which may become necessary in the UK in due course, they could then have three statuses which they could establish: hasn't got it, has got it, had it.
Serology tests - testing for the presence of virus-specific antibodies - can do this; I think Singapore announced a few days ago that they had developed one, and certainly labs around the world are working on it, but I don’t think they’re in general use yet. I’m sure they will become part of the arsenal - in particular they can (potentially) give a picture of the scale of sub-clinical infections, which could be very important in assessing mortality.
