Goats from 28 states were tested for antibodies to caprine arthritis-encephalitis virus. Of 3,790 goats, 1,175 (31%) tested positive, and of 196 herds tested, 143 (73%) had 1 or more seropositive members. This prevalence, based on serum samples from all goats in the participating herds, was lower than most rates reported in other studies. Such studies were based on fewer samples, incomplete sampling of herds, or smaller geographic base. Prevalence was highest in western Pacific and northern plains regions, increased with age to 3 years, was highest among goats on family-owned farms, and was lowest in the Angora breed. Differences in prevalence was not related to gender or size of herd.
对来自28个州的山羊进行了山羊关节炎-脑炎病毒抗体检测。在3790只山羊中，1175只（31%）检测呈阳性，在检测的196个畜群中，143个（73%）有1只或更多血清反应阳性的成员。基于参与畜群中所有山羊的血清样本得出的这一患病率低于其他研究报告的大多数比率。此类研究基于较少的样本、畜群抽样不完整或地理范围较小。患病率在西太平洋和北部平原地区最高，随年龄增长至3岁时上升，在家庭农场饲养的山羊中最高，在安哥拉品种中最低。患病率的差异与性别或畜群规模无关。
