Abstract

Increasing utilization of arable land in southwestern Venezuela has led to a potential increase in human exposure to arbovirus infections. Since previous studies in the Catatumbo region of this area documented the presence of eastern equine encephalitis (EEE) and Venezuelan equine encephalitis (VEE) viruses, an attempt was made to study the transmission and maintenance of these viruses from 1973 to 1981. Isolations of EEE, VEE ID strains, Una, Itaqui , and Moju viruses were repeatedly obtained from mosquitoes, mostly Culex ( Melanoconion ) spp. and sentinel hamsters. The results indicate that these viruses constitute a potential hazard to public health in the area. Further, the strategic location of the Catatumbo region, between enzootic tropical foci of arboviruses, may provide circumstances and conditions for study of both enzootic maintenance and movement of these viruses.

摘要

委内瑞拉西南部耕地利用的增加导致人类接触虫媒病毒感染的可能性增加。由于此前对该地区卡塔通博地区的研究记录了东部马脑炎（EEE）病毒和委内瑞拉马脑炎（VEE）病毒的存在，1973年至1981年期间曾试图研究这些病毒的传播和维持情况。EEE、VEE ID株、乌纳、伊塔基和莫茹病毒多次从蚊子（主要是库蚊属（黑蚊亚属）物种）和哨兵仓鼠中分离出来。结果表明，这些病毒对该地区的公众健康构成潜在危害。此外，卡塔通博地区位于虫媒病毒的热带动物疫源地之间的战略位置，可能为研究这些病毒的动物疫源性维持和传播提供环境和条件。
