I used to think this as well but unfortunately the excess death toll was the breaking point, if people had this quite readily here in winter you’d have expected the excess deaths to be that of a really bad flu season, which they weren't. It’s intriguing though, remember the man in France who had it in late December, and wasn’t diagnosed until months later when they retested samples.
I wonder if we will ever know.
I think we have had this discussion before - but this could be the second wave
Then again someone pointed out as this isn’t there flu there is a chance it would have one.
