I've only read this [1] before, and its not a bad story, but I wonder how sure you can be without knowing every corona virus strain in the region, it can still be from a strain we haven't sequenced. Also, it is more likely a something like this gets discovered in a major city vs some rural backwater, because they have more educated doctors there and more patience to detect a pattern.
