An outbreak of epizootic haemorrhagic disease virus (EHDV) in cattle in Israel in 2006 enabled a comparison of the spatial distribution of epidemic exposure to EHDV with that of exposure to bluetongue virus (BTV), which is endemic in the country. The seroprevalence of both viruses was examined in 1650 serum samples collected from 139 farms representative of the spatial distribution of dairy cattle in Israel. A significant association between exposure to EHDV and BTV was demonstrated in both univariate and multivariate analyses. Recent exposure to BTV and EHDV (demonstrated by seroprevalence in calves) was clustered in different geographical locations, indicating that the two viruses had different patterns of spread, that of EHDV being influenced by winds and terrain barriers and that of BTV by herd immunity.
2006 年，以色列爆发了牛传染性出血性疾病病毒（EHDV）疫情，这使我们能够比较 EHDV 流行暴露的空间分布与在该国流行的蓝舌病病毒（BTV）暴露的空间分布。在从代表以色列奶牛空间分布的 139 个农场采集的 1650 份血清样本中，检测了这两种病毒的血清阳性率。单变量和多变量分析均表明，EHDV 和 BTV 的暴露存在显著相关性。BTV 和 EHDV 的近期暴露（通过犊牛血清阳性率证明）在不同的地理位置聚集，表明这两种病毒的传播模式不同，EHDV 的传播受风和地形障碍的影响，而 BTV 的传播则受群体免疫的影响。
