A BRIEF REVIEW OF THE COLUMBID ALPHAHERPESVIRUS-1 INFECTION WORLDWIDE

Pigeon Herpesvirus infection is a widespread disease of pigeons caused by Columbid alphaherpesvirus-1 (CoHV-1), a virus within the Herpesviridae family. This virus is detected worldwide in pigeons and other bird species, especially raptors (owls, falcons, hawks, and eagles). Columbid alphaherpesvirus-1 was first described in the USA, with records dating back to 1943. The main clinical signs of CoHV-1 infection are respiratory and nervous, in addition to nonspecific signs like diarrhoea, vomiting, depression, and anorexia. The virus contributes to young pigeon disease syndrome (YPDS), a condition that affects young pigeons and causes high mortalities. This study aims to provide information about the virus, its transmission, the clinical symptoms, and postmortem lesions in pigeons and other species, the developed diagnostic tools for virus detection, and the disease control methods. As well as this review has also utilized an approach to map CoHV-1-related research papers to understand its research scene and virus world distribution.
