1999年，美国加州圣卡塔利纳岛的狐（Urocyonlittoraliscatalinae）数量急剧下降，其东部分布区面积约减少95%，占该岛面积的87%。在1999年10月至2000年4月的调查期间，活狐狸的证据急剧减少。在下降期间唯一的尸体死于犬瘟热病毒（CDV）和弓形虫病的共同感染。用聚合酶链反应（PCR）对病毒P基因进行序列分析，结果表明该病毒与来自美国大陆的浣熊（Procyonlotor）的犬瘟热病毒（CDV）密切相关。1999-2000年，在下降后的岛屿东部，10只狐狸中有9只有暴露于CDV的血清学证据，而1998年在该地区捕获的19只狐狸中只有4只有CDV抗体反应。确认CDV在一个死亡的狐狸，暴露于CDV在东端狐狸在1999-2000年与1998年相比，和文件的浣熊介绍到岛上的证据，暗示犬瘟热作为人口下降的原因。
The island fox (Urocyon littoralis catalinae) population on Santa Catalina Island, California, USA declined precipitously in 1999 with an approximate 95% reduction on their eastern range, an area representing 87% of the island. During this investigation, between October 1999 and April 2000, evidence of live foxes dramatically decreased. The only carcass recovered during the decline succumbed to a co-infection of canine distemper virus (CDV) and toxoplasmosis. Sequence analysis of the viral P gene, derived by polymerase chain reaction, indicated that the virus was closely related to CDV from a mainland USA raccoon (Procyon lotor). Nine of 10 foxes trapped in 1999–2000, on the eastern portion of the island after the decline, had serologic evidence of exposure to CDV, whereas only four of 19 foxes trapped in this region in 1998 had antibodies reactive against CDV. The confirmation of CDV in one deceased fox, evidence of exposure to CDV in east-end foxes in 1999–2000 compared to 1998, and documentation of raccoon introductions to the island, implicates canine distemper as the cause of the population decline.
