The Regional Representation for Asia and the Pacific office organised a webinar on Equine Rhinopneumonitis (Infection with Equid Herpesvirus 1 and 4), in the larger context of the World Organisation for Animal Health (WOAH) regional project on International Horse Movement in Asia and the Pacific.
Equine Rhinopneumonitis (ER, WOAH Technical Disease Card) is a collective term for any one of several contagious, clinical disease entities of equids that may occur as a result of infection by either of two closely related herpesviruses, equid herpesvirus-1 and -4 (EHV-1 and EHV-4). Infection with EHV-1 is listed by the OIE. EHV-1 and EHV-4 are endemic in most domestic equine populations worldwide.
Primary infection by either EHV-1 or EHV-4 is characterised by upper respiratory tract disease of varying severity that is related to the age and immunological status of the infected animal. EHV-1 also causes the more serious complications of abortion, perinatal foal death, or paralytic neurological disease (equine herpesvirus myeloencephalopathy). EHV-4 has been associated with sporadic cases of abortion, but not the large outbreaks associated with EHV-1. Like other herpesviruses, EHV-1 and 4 induce long-lasting latent infections and can be reactivated following stress or pregnancy. Most horses are likely to be re-infected multiple times during their lifetime, often mildly or subclinically. Detection of viral DNA or anti-EHV antibodies should therefore be interpreted with care.
The objectives of the webinar included:
Speakers included experts from FEI, UK USA and WOAH and WOAH Reference Laboratories in Ireland and Japan.
