采用寄主库蚊（库蚊）和哨岗鸡（库蚊）进行血清转化试验，对1991年和1992年Coachella谷西部马脑脊髓炎和圣路易斯脑炎病毒发生和传播的时空格局进行了研究。这两种病毒首先在研究区东南角毗邻索尔顿海的盐沼中被反复检测到，然后向西北的淡水沼泽、农业和居民栖息地传播。病毒传播相对较慢（<1公里/天），可能是由分散的寻找宿主的蚊子完成的。季节早期病毒活动的反复恢复表明，这两种病毒可能在盐沼生境中季节性地持续存在。
Temporal and spatial patterns in the initiation and dissemination of western equine encephalomyelitis and St. Louis encephalitis virus activity in Coachella Valley during 1991 and 1992 were detected by testing pools of host-seekingCulex tarsalisCoquillett for virus infection and sentinel chickens for seroconversions. Both viruses repeatedly were detected first at a salt marsh adjacent to the Salton Sea in the southeastern corner of the study area and then disseminated to the northwest to freshwater marsh, agricultural, and residential habitats. Virus dissemination was relatively slow (<1 km/d) and may have been accomplished by dispersive host-seeking mosquitoes. Repeated early-season recovery of virus activity indicated that both viruses may persist interseasonally in salt marsh habitat.
