Saint Louis encephalitis virus (SLEV), West Nile virus (WNV) and Ilheus virus (ILHV) are flaviviruses maintained by enzootic transmission networks between mosquitoes and birds. They have been detected in South America, with no records for Paraguay. We detected the presence of neutralizing antibodies for SLEV, WNV and ILHV in free-ranging birds collected in Paraguay (2016-2018). Four positive samples were detected in resident birds: one SLEV (rufous-bellied thrush), one WNV (barred antshrike) and two ILHV (white-tipped dove and shiny cowbird). These results bring new information about enzootic activity of flaviviruses in Paraguay.
圣路易斯脑炎病毒（SLEV）、西尼罗河病毒（WNV）和伊蚊病毒（ILHV）是黄病毒属，通过蚊子和鸟类之间的地方性传播网络维持。这些病毒在南美洲被检测到，但巴拉圭没有记录。我们在巴拉圭（2016-2018 年）收集的自由放养鸟类中检测到针对 SLEV、WNV 和 ILHV 的中和抗体。在留鸟中检测到 4 个阳性样本：一个 SLEV（红腹鸫），一个 WNV（条纹蚁鸟）和两个 ILHV（白翅鸽和光滑牛鹂）。这些结果提供了有关巴拉圭黄病毒地方性活动的新信息。
