摘要：Wildlife trade and emerging infectious diseases pose significant threats to human and animalhealth and global biodiversity. Legal and illegal trade in domestic and wild birds has played a significantrole in the global spread of highly pathogenic avian influenza H5N1, which has killed more than 240 people,many millions of poultry, and an unknown number of wild birds and mammals, including endangeredspecies, since 2003. This 2007 study provides evidence for a significant decline in the scale of the wildbird trade in Hanoi since previous surveys in 2000 (39.7% decline) and 2003 (74.1% decline). We attributethis to the enforcement of Vietnam's Law 169/2005/QD UBND, introduced in 2005, which prohibits themovement and sale of wild and ornamental birds in cities. Nevertheless, 91.3% (21/23) of bird vendorsperceived no risk of H5N1 infection from their birds, and the trade continues, albeit at reduced levels, inopen market shops. These findings highlight the importance of continued law enforcement to maintain thistrade reduction and the associated benefits to human and animal health and biodiversity conservation
