In the second episode of our two-part series on the current avian influenza crisis, WCS Wild Audio’s Hannah Kaplan looks at the rise of this new, more deadly strain in domestic poultry farming. 

In places like Cambodia, such farms have become a breeding ground for the virus, and the last five years have seen a dramatic increase in rates of infection of wild birds that share the same habitats.  

Meanwhile, scientists continue to track the growing threat to mammals, with the recent transmission to dairy cows in the US causing new concerns of potential new spillover to wildlife and people.
