No validated specific anti-equine herpesviral treatments are currently available. Any necessary treatment of clinical abnormalities and complications will be determined by the attending veterinary surgeon.
Good stud management and vaccination of all horses against EHV-1 and EHV-4 is recommended as a general principle (see Prevention above). The costs of prevention are likely to be far less than the costs associated with an abortion storm and significantly less than the disruption following a single abortion.
When cases of EHV neurological disease occur, caution must be exercised when considering the vaccination of previously unvaccinated horses either on the same premises or those that have recently left. The latter may have had contact with infection and may therefore be in the process of incubating the disease. Experience suggests that vaccination during the incubation stage can increase the chances of neurological signs.
