A preliminary serological survey was carried out to assess the likelihood of influenza A (IA) infection in wild boar and begin to characterize the role of wild boar in the epidemiology of the IA virus (IAV). Sera collected from 120 wild boar that were hunted in 2014 were tested. To detect antibodies to IA, a blocking the enzyme-linked immunosorbent assay (ELISA) was used. Thirty boar were collected from each of four oblasts in the north central and northwestern regions of Ukraine. Antibodies against IAV were detected in 27 samples (22.5%; 95% confidence interval 16.0–30.8) and in at least some of the wild boar from all of the four oblasts. This preliminary survey of IA antibodies in wild boar populations of northern Ukraine indicates a substantial frequency of exposure to IAV throughout the region. Infection of wild boar populations could provide an alternative or additional route for spillover from wild populations to domestic animals and humans.
