The Animal and Plant Health Inspection Service (APHIS) has been tracking cases of Equine Herpesvirus (EHV-1) since the first cases of the outbreak were reported in early May. With its final situation report issued on June 23, APHIS reports no new cases of the disease.
According to the APHIS final report, there were a total of 57 confirmed cases of EHV-1, 33 confirmed cases of EHM and 13 equine deaths, including euthanasias, suspected or confirmed to be a result of the outbreak.
The incident forced many stables into quarantine and caused the cancellation of many shows and events in the western United States. With no new cases reported, APHIS has officially declared the outbreak to be contained.
