Emerging infectious diseases are a major threat to biodiversity and an important public health issue. West Nile virus (WNV) is emerging vector-borne zoonotic arbovirus that currently broadening its distribution in Europe. The evidence of WNV circulating resident migratory species has implications for both animal health, should therefore be studied depth. An integrated surveillance program, namely birds, essential reducing the risk infection human populations within One Health principles. In present study, wild birds admitted wildlife rehabilitation centres Portugal were sampled. Two-hundred eight blood samples assayed serologically antibodies WNV, by using commercial ELISA kit. overall seroprevalence 19.6% (95% confidence interval [CI]: 13.7-26.7%) was observed. Antibodies detected 13 (35.1%) different birds. Accipitriformes (26.7%; 95% CI: 18.5-36.2%) Strigiformes 14.6-42.0%) orders with highest recorded. There no statistically significant differences (p = 0.725) between geographical regions (NUTS II) studied, but difference 0.017) found gender (male: 34.4%; female: 4.8%). A higher adults (32.1%) compared juvenile (9.3%) 0.014), age considered factor (odds ratio 1.4; 0.5–4.0). More epidemiological studies needed Portugal, since actual spread throughout country unknown.
