The Texas Animal Health Commission (TAHC) has no “confirmed” or “suspect” cases of the neurologic form of EHV-1 to report today. TAHC officials continue releasing primary traced horses and their cohorts (stablemates) that attended the Ogden, Utah, NCHA event.
Currently 16 known horses in Texas that attended the event and 185 cohorts (stablemates) remain under movement restrictions. There are a total of ten premises that have been exposed and those premises are in the following counties: Randall, Parker, Jack, Kerr and Mills counties.
TAHC and Texas veterinarians continue to investigate new situations statewide where horses are displaying symptoms consistent with that of the neurologic form of EHV-1.
If traveling out of state, TAHC officials urge horse owners to check with the state of destination before traveling. A downloadable list of contact information for all 50 state animal health agencies may be found on the U.S. Animal Association website (http://www.usaha.org/Reference/FederalStateAnimalHelalth.aspx) or on the USDA website (http://www.aphis.usda.gov/import_export/animals/animal_import/animal_imports_states.shtml).
The TAHC will post another Texas EHV-1 update tomorrow, Thursday, May 26 at 5:30 p.m. A new national report from USDA will also be available Friday, May 27.

May 20, 2011 – Texas Animal Health Commission (TAHC) officials are continuing to trace exposed horses that attended the National Cutting Horse Association (NCHA) Western National Championships event that ended on May 8 in Ogden, Utah that were potentially exposed to Equine Herpesvirus-1 (EHV-1). There are now 25 known horses in Texas that attended the event and 336 more cohorts (stablemates) of the 25 that are currently being held under movement restrictions across the state. The good news is that no new cases have been reported today. Texas still only has one confirmed case and one suspect case reported. The epidemiological investigation continues however, and Texas horse owners must be vigilant of the possibility that exposed horses may still be incubating the disease.
TAHC continues to suggest that horse owners closely evaluate the risk of participating in upcoming events scheduled for this weekend and/or co-mingling their horses with other horses and equipment (trailers) of unknown history. Because the incubation period is usually about 4-6 days or less, even a one week voluntary stop movement may be enough to nip the cycle of transmission between horses before it grows in scope. The TAHC will re-evaluate this position after analyzing new case data or other epidemiological information that may be disclosed over the weekend.
Horse owners should contact event organizers in advance to ensure that scheduled events have not been cancelled. Some other states have established emergency rules for entry as a result of this situation, so if interstate travel is planned, owners and/or veterinarians writing health certificates should check in advance to ensure they meet all entry requirements. Finally, it is recommended that all newly purchased horses or introduced horses to a premise should be isolated to help.
Another EHV-1 update will be sent out Monday evening. For information regarding EHV-1, visit www.tahc.state.tx.us. Several useful links can also be accessed through our website.
