All equine species moving interstate must be tested, with a negative result, within 

 6 months before entry and also must be accompanied by a permit, signed by an 

 accredited veterinarian, that describes the animal. 



Controlling the spread of EIAv involves minimizing or eliminating contact of healthy 

 horses with the secretions, excretions, and blood of EIAv-infected horses. Once the 

 reservoirs of EIAv are identified, separated, and maintained a safe distance from 

 the other horses, the transmission of EIAv is broken. Until all horses are tested, 

 precautions should be taken to prevent commingling with horses that do not 

 originate from test-negative farms or that have been exposed to test-positive horses. 

 All diagnostic laboratories are required to report positive test results to Federal and 

 State authorities for appropriate action. 



When an equine has a positive result on an official test for EIA, the animal must be 

 placed under quarantine within 24 hours after positive test results are known in order 

 to permit confirmation testing and to prevent further exposure of other equines. The 

 equine must remain in quarantine until final classification and disposition are made. 



All exposed equines (either individual or within a herd) within 200 yards of the 

 location where a reactor equine is or was maintained must also be placed under 

 quarantine. The quarantine area must provide no less than 200 yards of separation 

 from all other equines. The quarantine area and the quarantined equines therein 

 must be monitored periodically by regulatory personnel to ensure that provisions of 

 the quarantine are not being violated. 



APHIS-VS created the EIA Uniform Methods and Rules to implement and conduct 

 a national control program for EIA. Additional information regarding the control 

 program may be found at http://www.aphis.usda.gov/vs/nahps/equine/eia or be 

 obtained by contacting the local APHIS-VS Area Office.
