Oh dear, just had a read of Anatidae migration and h5n1 paper; authors inc Joseph Domenech and Juan Lubroth of FAO. Looks to be based on various barely founded assumptions.
Why haven’t they also strongly considered the flyways in east Asia, say?
– where patterns don’t follow migration routes. [Here I am in Hong Kong; evidence here powerfully against ducks being major carriers H5N1)
A few quotes:
…
The search for wild bird species carrying HPAI H5N1 virus is in progress and awaits further classification.
…
The broad approach adopted in this study has clear limitations
Sad people amongst authors, with a strong and clear bias towards poultry industry (Joseph Domenech is there, I see: long a cheerleader for blaming wild birds for spread, avoiding notions it’s really the poultry trade to blame).
There’s little about how it’s not efficient for ducks to spread via oral tracts – no notion that wild avian flus spread thro faeces as they have evolved to transmit thro most efficient mechanisms.
Only scant coverage of trade routes, as much discussed here on aiwatch. The situation in east Asia just skated over.
Appalling. (Tho for those involved in the poultry industry gravy train, must be considered a boost after an autumn of – so far – zero transmission by wild birds. New Sci and its poultry magazines publishing publisher will surely like it!)
