A domestic ruminants serosurvey of Rift valley fever (RVF) neutralizing antibodies has been carried out during three years after the 1987 epidemic in the Senegal River Basin. Authors present results from the 1990 serosurvey that are matched with the preview surveys. Out of 1,225 ongulate tested, 17.2% had RVF virus antibodies. There is a global decrease in the herds immunity since the epizootic manifestation associated with the 1987 epidemic. Significant differences in seroprevalence are observed from the delta (28.5%) to the lower (17.9%) and middle valley (6.1%) of the Senegal river. Cattle are more likely to be with an higher seroprevalence than goat and sheep.
在塞内加尔河流域1987年裂谷热疫情爆发后的三年里，开展了一项关于家畜裂谷热（RVF）中和抗体的血清学调查。作者展示了1990年血清学调查的结果，并与之前的调查结果进行了对比。在1225头有蹄类动物的检测中，17.2%的动物含有裂谷热病毒抗体。自1987年疫情相关的动物流行病表现以来，畜群免疫力总体呈下降趋势。从塞内加尔河三角洲（28.5%）到下游（17.9%）和中游（6.1%），血清阳性率存在显著差异。牛的血清阳性率比山羊和绵羊更高。
