The A (H5N1) pressure has turn out to be “a global zoonotic animal pandemic”, Farrar mentioned.

“The great concern of course is that in… infecting ducks and chickens and then increasingly mammals, that virus now evolves and develops the ability to infect humans and then critically the ability to go from human to human.”

So far, there is no such thing as a proof that the influenza A(H5N1) virus is spreading between people.

But within the a whole lot of circumstances the place people have been contaminated via contact with animals, “the mortality rate is extraordinarily high”, Farrar mentioned.

From 2003 to April 1 this yr, the WHO mentioned it had recorded 463 deaths from 889 human circumstances throughout 23 nations, placing the case fatality fee at 52 %.

In a worrying improvement, US authorities earlier this month mentioned an individual in Texas was recovering from chook flu after being uncovered to dairy cattle.

“It’s a tragic thing to say, but if I get infected with H5N1 and I die, that’s the end of it. If I go around the community and I spread it to somebody else then you start the cycle.”

He mentioned efforts have been below manner in direction of the event of vaccines and therapeutics for H5N1, and pressured the necessity to make sure that regional and nationwide well being authorities world wide have the capability to diagnose the virus.

This was being carried out in order that “if H5N1 did come across to humans, with human-to-human transmission”, the world can be “in a position to immediately respond”, Farrar mentioned, urging equitable entry to vaccines, therapeutics and diagnostics.
