Dr Jeremy Farrar, Chief Scientist on the World Well being Group (WHO), stated that the avian influenza virus – which is often known as H5N1 – has had an “extraordinarily excessive” mortality fee among the many a number of hundred individuals recognized to have been contaminated with it thus far.
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 grow to be a world zoonotic – animal – pandemic,” he stated.
“The good concern, in fact, 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 USA, the WHO senior official urged additional shut monitoring and investigation by public well being authorities, “as a result of it could evolve into transmitting in numerous methods”.

He added: “Do the milking constructions of cows create aerosols? Is it the surroundings which they’re residing in? Is it the transport system that’s spreading this across the nation? It is a large concern and I feel we’ve to … make it possible for if H5N1 did come throughout to people with human-to-human transmission, that we had been ready 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 – world pandemic.
The initiative was initially sparked by the COVID-19 emergency and the popularity that there was a lack 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 enchantment
To counter this, the WHO led consultations with 4 main public well being businesses from Africa, China, Europe and the USA, earlier than asserting settlement on quite a few agreed new phrases. These embody “infectious respiratory particles” or “IRPs”, which ought to be used as a substitute 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 deal with ever “extra complicated and extra frequent epidemics and pandemics”, Dr Farrar informed journalists in Geneva.
“It is a vastly essential first step. However subsequent, we have to preserve the disciplines, the specialists 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 right way to management these infections higher than we’ve performed previously.”
On the potential HN51 public well being threat, the WHO Chief Scientist cautioned that vaccine growth was not “the place we should be”. Neither was it the case that regional workplaces and nation workplaces and public well being authorities around the globe have the potential to diagnose H5N1, he famous.
