Equine Diseases

In Michigan, there are number of reportable diseases for equine, including Eastern Equine Encephalitis (EEE), West Nile virus (WNV), equine herpesvirus (EHV-1 and EHV-4), equine infectious anemia (EIA), and strangles.

If a reportable disease is suspected and/or confirmed in an equid, please report the case to the Michigan Department of Agriculture and Rural Development (MDARD) by submitting a completed Reporting a Reportable Animal Disease (RRAD) Form to mireportableanimal@michigan.gov or by calling 800-292-3939 (daytime) or 517-373-0440 (after-hours).  

When reporting a potential case of an Emergency Disease, be sure to speak directly to a person and don’t leave a voicemail or submit a completed RRAD form.

If a Michigan equid is suspected of having WNV or EEE, please contact MDARD at 800-292-3939 to discuss the possibility of covering these testing costs through funding. If funds are available and MDARD approves the testing, samples must be submitted to the Michigan State University Veterinary Diagnostic Laboratory.
