除了2002年在智利的商品家禽中爆发禽流感外，南美洲几乎没有关于禽流感的报告。然而，对自由飞行的鸟类的监视是有限的。2001年，从玻利维亚为禽流感病毒和禽副粘病毒监测研究收集的样本中分离出一种禽流感病毒。该分离株经基因测序鉴定为H7N3病毒。对所有8个基因的分析显示，其中5个基因与2002年智利的H7N3病毒最密切相关。两个基因与北美野生水禽病毒谱系最密切相关，一个基因与来自南美洲的马流感病毒最密切相关。
Apart from an outbreak in commercial poultry in Chile in 2002, there have been few reports of avian influenza in South America. However, surveillance in free-flying birds has been limited. An avian influenza virus was isolated from a Cinnamon Teal (Alias cyanoptera) in Bolivia in 2001 from samples collected for an avian influenza virus and avian paramyxovirus surveillance study. This isolate was determined to be an H7N3 virus by gene sequencing. Analysis of all eight genes revealed that five genes were most closely related to the H7N3 in Chile in 2002. Two genes were most closely related to North American wild aquatic bird virus lineages and one gene was most closely related to an equine influenza virus from South America.
