Widespread geographic movement and extensive comingling of exhibition swine facilitates the spread and transmission of infectious pathogens. Nasal samples were collected from 2862 pigs at 102 exhibitions and tested for five pathogens. At least one pathogen was molecularly detected in pigs at 63 (61.8%) exhibitions. Influenza A virus was most prevalent and was detected in 498 (17.4%) samples. Influenza D virus was detected in two (0.07%) samples. More than one pathogen was detected in 165 (5.8%) samples. Influenza A virus remains a top threat to animal and human health, but other pathogens may be disseminated through the exhibition swine population.

通过在农业展览会中检测到五种呼吸道病原体，评估展览会猪是否是传染病的潜在传播者。

展翅猪的广泛地理移动和广泛混合促进了传染性病原体的传播和传播。在102个展览会上从2862头猪中收集了鼻样本，并检测了五种病原体。在63（61.8％）个展览中，在猪中至少检测到一种病原体。甲型流感病毒最为流行，在498个样本中（17.4％）被检测到。在两个（0.07％）样本中检测到D型流感病毒。在165个样本中（5.8％）检测到一种以上的病原体。甲型流感病毒仍然是对动物和人类健康的最大威胁，但其他病原体可能会通过展览猪群传播。
