This has been a well kept secret for decades ...the higher the specialisation the greater the vulnerability.
Small is beautiful we once used to say. Only problem it's not profitable.
I'm afraid it takes more than this to generally act on this knowledge.
FYI (you probably know already) I read some worrying news a few days ago on the possibly merging of two different genotypes of H5N1 in Thailand.
However when I would search the info today I couldn't open The Nation... obviously closed down because some major protest against the junta are to
take place in Bangkok today. Sure hope it's only temporary.
Anyway I found the info on a discussion board
CurEvents.com. I've never seen it before
(again sofi, you probably have). Very qualified discussions going on there.
Here's the snippet with the story in question.

Experts fear bird-flu virus would mutate
March 24, 2007
Experts Friday voiced concern over the possibility that the two different genotypes, called "sub-clades", of the H5N1 bird-flu virus found in
Thailand could meet and merge into an unknown and "unpredictable" mutated form.
A Chulalongkorn University has found that a virus sample from Nakhon Phanom province in the Northeast was of a strain newly observed in Thailand and
more closely related to H5N1 strains that have been circulating since 2005 in southeast China.
In contrast, H5N1 samples from Phichit province in the lower North region were similar to the cluster of samples isolated during 2004 and 2005
outbreaks in Thailand and Vietnam, said Prof Dr Yong Poovorawan, author of the Chulalongkorn University study.
The viruses isolated from Phichit belonged to genotype Z, whereas the virus isolated from Nakhon Phanom belonged to genotype V, he wrote in his
report.
The latest bird-flu outbreak, in the Northeast province of Mukdahan, has raised concerns that the genotype V virus from the Northeast could spread to
meet with the genotype Z virus endemic in the lower North and Central region, said veterinarian Rakthai Ngampak, head of the Department of Livestock
Development's Bird Flu Control Centre.
