Good morning everyone,
We are touching base about the current EHV outbreak in Texas. While there have been no confirmed cases in Colorado yet, there were horses from the state in attendance of events that had exposure. We have decided out of an abundance of caution, to quarantine our facility and not allow horses off the property at this time. This includes trail riding. We know this is inconvenient and the risk is minimal, but it is not zero.
I will include some general information below as well as a few links with more info. As always feel free to reach out with any questions.
EHV symptoms in horses can range from mild respiratory signs to severe neurological disease and abortion. Common symptoms include fever, nasal discharge, lethargy, and coughing, while the neurologic form (EHM) presents with incoordination, hind limb weakness, and an inability to urinate. Pregnant mares may experience late-term abortions.
Respiratory
• Fever (often biphasic)
• Nasal discharge (clear and colorless)
• Swollen lymph nodes, particularly under the jaw
• Depression or lethargy
• Coughing
• Loss of appetite
Neurologic (Equine Herpesvirus Myeloencephalopathy - EHM)
• Fever
• Weakness and incoordination
• Difficulty urinating or urine dribbling
• Lethargy
• Loss of tail tone
• Hind limb paralysis or inability to stand
• Loss of sensation in the hind limbs and tail.
What to do
• If you suspect your horse to be ill or acting “off” please notify Nic or Marie immediately
• Contact a veterinarian immediately if you suspect EHV, especially if neurologic symptoms appear.
• You can take temperatures daily as well. At this time we do not deem this as necessary since we haven’t had any horses travel out of state or off property and be directly exposed to the outbreak.
This post is not intended to create panic, merely educate people about the outbreak and disease itself. Our risk is extremely low, we are just taking measures out of an abundance of caution.

Equine herpesviruses are very common DNA viruses in horse populations worldwide. The two most significant are EHV-1, which causes respiratory disease, abortion, and neurologic disease; and EHV-4, which primarily causes respiratory disease and only occasionally causes abortion or neurologic disease.....
