It's not the first time that avian flu has crossed from bird to human... it's done it on rare occasions since it was discover in 2013.
There have only been 2 cases of suspected human to human transmission.
The issue is when a virus mutates to make human to human transmission more possible... like the fast mutations of SARS-CoV-2 or Covid19 |

This could be just the start... |

Often viruses have species barriers, bird viruses often need an intermediary to infect humans I think its most often pigs, as chickens and pigs are often kept in close proximity, if we're exposed often and for prolonged periods theres more chance the virus will nump the barrier.
Viruses are doing what viruses do seek out a new host,if it finds a species that isn't its normal host it might be unlucky or in this case lucky its found a weakness it hadn't exploited before probably through a mutation in its original host.
nothing new in viruses changing/mutating. If they didn't they'd very quickly be extinct.
On a list of things I'd be worried about this ain't even on it.  |

Let’s hope the birds don’t start catching man flu  |

Which as I said... is not the first time. Its the first time it's happened in the UK but its been happening since 2013...
Having seen some of your recent posts, are you OK? Have you got people to talk to, you seem to have some.rosing anxiety levels. |

I’d be far more worried if a non human man had caught it! |

"This is how it all starts..
If it's not serious then why do they slaughter these birds and put exclusion zones on.
More to this than meets the eye "
Because its deadly and spreds really quickly among birds, who by the fact they are birds, are hard to control and stop them from travelling miles....
In 2001 many of my friends were or were nearly put out of business when 10 million livestock were culled during the foot and mouth outbreak |

It's pigs needed as an intermediary yes, but the reason is biochemical.
Human receptors for influenza virus are the same as pig receptors, but slightly different to bird receptors.
Pigs have both the "human" version of the receptor but also the "bird" version, so pigs can act as mutation vessels for influenza viruses that can then possess suitable surface proteins to fit into the "human" receptors.
This is why H1N1 "swine" flu was much more of a human health concern than H5N1 "bird" flu.
If humans acquire a very high infectious dose of "bird" flu, the sheer numbers mean sufficient binding may happen of unmutated "bird" flu, thus causing human infection but this is pretty rare. |
