So various media are reporting a new pandemic flu virus discovered in China. What does this actually mean? Let's look at the original paper. Actually, that's not so easy to do because—unconscionably in my opinion— has put it behind a paywall.
Great. Another H1N1 strain of influenza, with pandemic potential, found brewing in pigs in China, in a commendable surveillance regime. Prevalent Eurasian avian-like H1N1 swine influenza virus with 2009 pandemic viral genes facilitating human infection
There is a lot of media attention to the swine flu PNAS study from China. Everybody is sensitized now because of COVID-19. And it is important to keep an eye on these viruses. But there is no reason for panic and no imminent danger.
A reminder that influenza lineages with pandemic potential are lurking ...
This Chinese G4 virus reproduces more in human airways, has efficient infectivity & aerosol transmission in ferrets. Low antigenic cross-reactivity of human influenza vaccine strains indicates that preexisting population immunity may not be protective.

Here is the article referred to by the BBC: Prevalent Eurasian avian-like H1N1 swine influenza virus with 2009 pandemic viral genes facilitating human infection PNAS
"We identify a recently emerged genotype 4 (G4) reassortant Eurasian avian-like #H1N1 #influenza virus [in #pigs], which ... has acquired increased human infectivity. Such infectivity ... raises concerns for the possible generation of pandemic viruses."
Just exactly what the world really needs now. "G4 EA H1N1 virus has acquired increased human infectivity."
Will be talking to on shortly after 4pm about the swine flu surveillance paper in PNAS. Nothing unusually alarming in it but a further reminder that pandemic surveillance and preparedness is super important
Lovely.. 20% seroprevalence amongst 20-35yo pig farm workers already.

How do we meme this one lads? Pig-chan or Swine-chan isn't as sexy as Corona-chan.

As we continue having greater capacity for screening zoonotic spillovers it will be interesting to get a better sense of how many viruses make it to the "seroprevalent in humans" phase without getting to the "transmitted between humans" phase
