Why unprecedented bird flu outbreaks sweeping the world are concerning scientists
Mass infections in wild birds pose a significant risk to vulnerable species, are hard to contain and increase the opportunity for the virus to spill over into people.

Researchers say that the virus seems to be spreading in wild birds more easily than ever before, making outbreaks particularly hard to contain. Wild birds help to transport the virus around the world, with their migration patterns determining when and where it will spread next. Regions in Asia and Europe will probably continue to see large outbreaks, and infections could creep into currently unaffected continents such as South America and Australia.

Ramey adds that only a fraction of cases in wild birds are diagnosed and reported. More monitoring could unveil the true magnitude of wild bird mortality, he says.
