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:
