Molecular investigation of the occurrence of herpesviruses in 228 wild birds in Piauí, northeastern Brazil, identified a herpesvirus in a migratory Wilson's Plover (Charadrius wilsonia). Genetic analysis supported its classification as a new strain, tentatively named Charadrius alphaherpesvirus 1, within the genus Mardivirus, broadening the herpesvirus host range in Charadriiformes.
Catenacci et al. (Wed,) studied this question.
