About EHV


New information since APHIS's May 19, 2011 report is in blue type.

Horses categorized in EHV-1 or EHM suspect categories or as EHV-1 confirmed in previous reports may change categories based on test results or development of additional clinical signs.

Categories:

Primary Exposed Horses: Horses that attended the Ogden, Utah event from April 29 to May 8.

Secondary Exposed Horses: Horses that subsequently came into direct contact with horses that attended the Ogden, Utah event.

Tertiary Exposed Horses: Horses with three degrees or more separation from direct contact with a horse that attended the Ogden, Utah event.

Exposed Premises: Premises with exposed horses.

Suspect EHV-1 case: A horse exposed to EHV-1 that develops fever (rectal temperature above 101.5ºF), but has no neurologic signs at this time.

Confirmed EHV-1 case: A suspect EHV-1 case with laboratory confirmation of EHV-1 infection, but has no neurologic signs at this time.

Suspect EHM case: A horse exposed to EHV-1 that develops neurologic signs. (Posterior incoordination, weakness, recumbency with inability to rise, and/or bladder atony are most commonly seen in EHM cases.)

Confirmed EHM case: A suspect EHM case with laboratory confirmation of EHV-1 infection.


**One confirmed EHM case previously reported was moved back to its home state
of New Mexico and is currently reflected in the New Mexico case report.
