“Reports of the effect of EI vary enormously – some horses have minimal signs with just an odd cough while others have lost their appetites, are coughing badly, have thick nasal discharges and are showing signs of depression,” Mr Christie said.
“If horses develop complications from EI they should receive proper veterinarian attention.”
Owners should monitor their horses and stay in contact with their veterinarian to receive advice in case the illness worsens.
Horses with EI should be rested in a dust-free, well-ventilated environment and owners should discuss supportive treatments with their veterinarian.
Particular care should be taken if animals are vulnerable to disease – pregnant mares, foals, stallions and older horses.
At least 30 days complete rest is recommended after infection, with a longer period being required if the fever lasts more than four days. Rest reduces the opportunity for secondary infection and speeds recovery.
Supportive treatments such as cough suppressants can help reduce complications.
For stallions or pregnant mares with very high fevers, anti-inflammatory drugs may be used on veterinary advice to avoid testicular degeneration in stallions or abortion in mares.
Contact your veterinarian if you have any concerns about the health of newborn foals.
Foals can deteriorate quickly if they contract EI. Prematurely born foals which are smaller in body size are more prone to the virus.
During the EI outbreak it is important that horse handlers implement a policy of strict personal disinfection and hygiene when handling all horses.
