Equine Herpes Virus Type 1 (EHV-1) (abortigenic and neurological strains) is a notifiable disease.
Equine Herpes Virus Type 1 (EHV-1) is the most important viral cause of abortion in horses. The virus is also the cause of respiratory disease (Equine rhinopneumonitis) and equine herpes virus encephalomyelitis (neurologic EHV-1)
EHV-1 is important to the equine industry, as it typically infects a wide range of cells and can potentially cause severe systemic illness. It has been proposed that there are two different variants of EHV-1: neuropathogenic and abortigenic. While the neuropathogenic strain of EHV-1 is considered exotic to Australia, the abortigenic strain is endemic in certain areas.
EHV-1 abortions usually occur in the last trimester of gestation, although they may occur earlier. Infected mares are typically asymptomatic although some can be pyrexic before aborting. Rarely, live foals are born with clinical signs of weakness and respiratory distress before death. An abortion storm involving several late gestation mares occurs infrequently due to the availability of rapid, sensitive and specific diagnostic tests for management of disease, and widespread vaccination.
Diagnosis is based on clinical history, histopathology and virology.
