There are a lot of people locally who think that it was here Nov/Dec. There is a travel link with China that fits with the timeline too. I can list numerous odd stories which people were talking about before covid appeared on the horizon. One includes someone who had a mysterious form of pneumonia. Doctors did all sorts of tests on and couldn't identify what caused it. He was ill for some considerable time.
The earliest case in France is thought to be at the end of December and thats thought to be via community transmission - though there is also some debate about how reliable that case is too. But there is other evidence emerging in other places in Europe about early cases and its not that much of an outlier when put into this context.
Whats interesting at present is the number of cases testing positive v the number of deaths - which does suggest perhaps the virus could have been in certain communities a lot longer than previously thought without being detected.
I also note in terms of excess deaths, the fact the end of last year was particularly mild, it does mean any deaths from covid could have been masked by an unusually low number of deaths from other seasonal illnesses.
It certainly within the realms of possibility that it being here in mid Dec is a reasonable theory and I do think that as time goes on, we will see more information slowly emerge that supports it.
Even if this particular man caught covid in hospital in January, that suggests that local transmission in hospitals was already occurring. And that begs the question, where did that come from? Dismissing the idea that he was admitted for covid, when he had all the symptoms, seems odd and really only takes things back to probably around mid January if you take into account how long it took him to be infected / someone else in the hospital setting being infected in someway. Thats still some weeks before the first known case in the UK.
Previous data has already suggested that for the peak to have occurred at the level it did in April, the virus MUST have been circulating freely in the community for AT LEAST three to four months.
So finding this case isn't hugely surprising nor unexpected tbh.
