Dr Jeremy Farrar, Chief Scientist on the World Well being Group (WHO), mentioned that the avian influenza virus – which is also referred to as H5N1 – has had an “extraordinarily excessive” mortality fee among the many a number of hundred individuals recognized to have been contaminated with it to this point.
Thus far, no human-to-human H5N1 transmission has been recorded.
“H5N1 is (an) influenza an infection, predominantly began in poultry and geese and has unfold successfully over the course of the final one or two years to develop into a world zoonotic – animal – pandemic,” he mentioned.
“The good concern, after all, is that in doing so and infecting geese and chickens – however now more and more mammals – that that virus now evolves and develops the power to contaminate people. After which critically, the power to go from human-to-human transmission.”

Commenting on an ongoing outbreak of H5N1 virus amongst dairy cows in the US, the WHO senior official urged additional shut monitoring and investigation by public well being authorities, “as a result of it might evolve into transmitting in several methods”.

He added: “Do the milking buildings of cows create aerosols? Is it the setting which they’re dwelling in? Is it the transport system that’s spreading this across the nation? This can be a big concern and I believe we’ve got to … ensure that if H5N1 did come throughout to people with human-to-human transmission, that we have been able to right away reply with entry equitably to vaccines, therapeutics and diagnostics.”
Equal to subsequent pandemic
The event comes because the WHO introduced up to date language to explain airborne pathogens, in a bid to extend worldwide cooperation within the occasion of a brand new – and anticipated – international pandemic.
The initiative was initially sparked by the COVID-19 emergency and the popularity that there was an absence of generally agreed phrases amongst medics and scientists to explain how the coronavirus was transmitted, which elevated the problem of overcoming it, Dr Farrar defined.
World attraction
To counter this, the WHO led consultations with 4 main public well being companies from Africa, China, Europe and the US, earlier than asserting settlement on quite a few agreed new phrases. These embrace “infectious respiratory particles” or “IRPs”, which ought to be used as an alternative of “aerosols” and “droplets”, to keep away from any confusion in regards to the dimension of the particles concerned.
Over and above the brand new terminology, the initiative cements the dedication of the worldwide group to sort out ever “extra advanced and extra frequent epidemics and pandemics”, Dr Farrar instructed journalists in Geneva.
“It is a massively necessary first step. However subsequent, we have to maintain the disciplines, the consultants collectively.
“We’re utilizing the identical terminology, the identical language, and now we have to do the science that gives the proof on tuberculosis, on COVID and different respiratory pathogens, in order that we all know the best way to management these infections higher than we’ve got performed prior to now.”
On the potential HN51 public well being danger, the WHO Chief Scientist cautioned that vaccine improvement was not “the place we should be”. Neither was it the case that regional places of work and nation places of work and public well being authorities world wide have the potential to diagnose H5N1, he famous.
