With recent events, this has really got me thinking about how important it is to have a biosecurity plan implemented into your barn. So, when outbreaks like this one do happen you can be prepared and know that you can handle whatever disease outbreak you may or your horses may come in contact with or be suspected of being in contact with.
I think it's important to better educate ourselves and to ensure the health of our horses that we love so much and do so much for us. I have been toying around with the idea of possibly turning this into an episode as I believe it's apart of being educated in the equine industry for all of us.
Would y'all want to hear an episode about biosecurity plans just let me know in the comments? If that would interest you at all. Also, let me know you're biosecurity plan if you already have one implemented in your barn!
What is Equine Herpesvirus (EHV)?
You've probably heard it called Rhinopneumonitis, a respiratory tract disease that results in "snotty noses," but EHV is more than that. Depending on the strain, this virus can also cause abortion in broodmares, and equine herpesvirus myeloencephalopathy (EHM) โ the often-deadly neurologic form of the disease.
Because EHV is endemic in many equine populations, most mature horses have developed some immunity through repeated natural infection. However, they remain a source of infection for other susceptible horses, like weaned foals and yearlings, who usually display symptoms of the respiratory form of the disease in autumn and winter. Performance and show horses are also more vulnerable to the disease, as they commingle with unfamiliar equines in close quarters while under stress from travel and competition.
Proper biosecurity protocols can help reduce EHV outbreaks and other disease transmission. A variety of vaccines are also available for protection against both the respiratory and abortive form of the disease, but there is no equine licensed vaccine at this time that has a label claim for protection against the neurologic form (EHM).
Consult your primary equine veterinarian to learn more about this disease and work with them to determine the optimal vaccine protocol for your horses.
