...the Beeb reports that a new strain of swine flu (G4 EA H1N1), which bears similarities to the 2009 pandemic flu (A/H1N1pdm09) and can be inoculated against using adapted versions of current flu vaccines, has appeared in pigs in China. It can spread from pigs to humans, but the danger of person-to-person transmission - while not imminent - is possible. Many have expressed concerns about the emergence of a new strain of flu in recent weeks.
This is intended to be a catch-all thread about G4 EA H1N1 swine flu; the moratorium on coronavirus-related misinformation does not currently extend to swine flu, but I will update this OP if and when it does. Food for thought: How far could this go? (Personal opinion - one of two ways. Either this peters out and we hear nothing more about it, or it winds up spreading massively over the winter and absolutely clobbering hospitals for a few months until the vaccines can be re-engineered as appropriate.)
