We identified four fundamental questions underlying these claims and requested supporting studies from FLI (which according to the German Government “possesses virus isolates of H5N1”):
1.Does H5N1 exist?
2.Is it pathogenic to animals?
3.Is it transmissible and pathogenic to humans, and does it have pandemic potential?
4.Have other causes for observed disease been studied?
Our analysis shows the papers do not satisfy our four basic questions. Claims of H5N1 pathogenicity and pandemic potential need to be challenged further.
