Usutu virus (USUV) and West Nile virus (WNV) are emerging pathogens that can cause neurological disease in humans. From March 2012 to June 2013, a sero-survey on wild birds was carried out to investigate the circulation of both viruses in Northwest (NW) Italy. Samples belonging to 47 different bird species have been collected using a volunteer based network and a wildlife rehabilitation center. Four of 297 serum samples had neutralizing antibodies against USUV (P=1.34%, IC 95% 0.36-3.4), while 10 of 233 samples tested positive for WNV (P=4.29%, IC 95% 2.07-7.75). Neutralizing antibodies for WNV were significantly more prevalent (p<0.001) in trans-Saharan migrants (P=21%, IC 95% 9.55-37.3) than in resident and short-distance birds, but no migratory habit-related differences were found for USUV. Antibodies in resident bird species suggest that both viruses are circulating in NW Italy.
乌苏图病毒（USUV）和西尼罗河病毒（WNV）是新兴病原体，可导致人类神经疾病。2012年3月至2013年6月，对野生鸟类进行了血清学调查，以研究这两种病毒在意大利西北部（NW）的传播情况。使用基于志愿者的网络和野生动物康复中心收集了属于47种不同鸟类的样本。297份血清样本中有4份具有针对USUV的中和抗体（P = 1.34%，95%置信区间0.36 - 3.4），而233份样本中有10份WNV检测呈阳性（P = 4.29%，95%置信区间2.07 - 7.75）。与常驻鸟类和短途鸟类相比，WNV的中和抗体在跨撒哈拉迁徙鸟类中显著更为普遍（p < 0.001）（P = 21%，95%置信区间9.55 - 37.3），但未发现与USUV相关的迁徙习性差异。常驻鸟类物种中的抗体表明这两种病毒都在意大利西北部传播。
