Experts warn bird flu poses ‘an existential threat’ to biodiversity, and a possible threat to humans

Mongabay Newscast

The current clade of H5N1 or bird flu is an "existential threat" to the world’s biodiversity, experts say. While it has infected more than 500 bird and mammal species on every continent except Australia, the number of human infections from the current clade (grouping) 2.3.4.4b is still comparatively small. U.S. dairy workers have recently become infected, and the virus could easily mutate to become more virulent, our guest says.

Joining the Mongabay Newscast to talk about it is Apoorva Mandavilli, a global health reporter for The New York Times. Mandavilli details what virologists and experts know about the human health risks associated with this latest clade, what nations are doing (or not doing) to help contain its spread, and why. She also details how environmental degradation and industrial agriculture help create the conditions for outbreaks like this to occur.
