A neutralizing antibody (NTAb) survey on UNA and Mayaro viruses in black howler monkeys (Aloutta caraya) from subtropical regions of Argentina and Paraguay was carried out. Risk factors for infection in monkeys were analyzed. No positive sera for Mayaro virus were detected. A prevalence of 73% (61/84) of NTAb against UNAV was detected with titers ranging from 20 to 1280. According to the statistical analysis performed, the monkey's age was a significant risk factor, but not the origin or sex. This is the first report of Alouatta caraya infection by UNAV and the first record of its activity in Paraguay.
对来自阿根廷和巴拉圭亚热带地区的黑吼猴（Aloutta caraya）进行了关于乌纳病毒（UNA）和马亚罗病毒的中和抗体（NTAb）调查。分析了猴子感染的风险因素。未检测到马亚罗病毒阳性血清。检测到73%（61/84）的猴子具有抗乌纳病毒的中和抗体，滴度范围为20至1280。根据所进行的统计分析，猴子的年龄是一个显著的风险因素，但来源或性别不是。这是关于黑吼猴感染乌纳病毒的首次报告，也是该病毒在巴拉圭活动的首次记录。
