USDA has released the fifth national EHV-1 situation report. There was one newly identified premise with a suspect or confirmed EHV/EHM case during this last reporting period. We continue to ask all horse owners and organizations to maintain a measured and informed response along with responsible ownership practices to further mitigate the economic and health implications of this current outbreak. A summary of the updated information is as follows:

Summary Information on Current Situation (as of 06/15/2011):

• A total of 90 confirmed EHV-1 or EHM cases have been reported in 10 states (AZ, CA, CO, ID, NM, NV, OK, OR, UT, WA)
• Of the 90 confirmed EHV/EHM cases, 54 (corrected from previous reports) cases are horses that were at the Ogden, Utah event.
• There are 13 horses associated with this incident that are dead or have been euthanized.
• There is 1 newly identified premises with suspect or confirmed cases identified this reporting period.

The complete USDA EHV-1 Situation Report provides detailed information on the number of exposed, positive, dead, and euthanized horses on a state by state level. The AHC anticipates USDA releasing another national situation report at the end of next week.
