Thank you again for expert comment.
I’d thought all the H5N1 forms causing trouble were broadly Z, and traced to Guangdong goose 1996 (then HK in 97).
Clearly too simplistic – and maybe I should again read the genotype Z paper and some more, inc one I’ve some memories you co-authored.
Google search, and about 88,700 results for “sims h5n1”; include (for others who read this thread):
