birds korea on h5n1 poultry flu

[Martin W]

Nial Moores of Birds Korea has produced an excellent – and long, detailed – Poultry Flu Update.

Contrast the wealth of info here, with the scatter-brained, information sparse material from those saying wild birds are spreading h5n1.

Info from Nial Moores of Birds Korea:

As background to the South Korean outbreaks, the following published information on AI sampling of wild bird populations in South Korea (provided today by Dr. Lee Hansoo), is especially useful:

Kim (2006) contains the following results of wild bird surveillance activity.

2003-04 winter: Tested 5,460 fecal samples, isolate 26 LPAI
2004-05 winter: Tested 3,970 fecal samples, isolate 34 LPAI
2005-06 winter: Tested 4,415 fecal samples, isolate 31 LPAI
2005-06 winter along DMZ area: Tested 1,900 fecal samples, isolate 46 LPAI

National Veterinary Research and Quarantine Service (NVRQS) teams tested the fecal sample of waterfowl in various areas since the 2003 AI outbreak, but they isolated only LPAI virus.

(During the current outbreak period, the NVRQS team apparently did not yet find any HPAI virus among the collected waterfowl samples.)
