    Epizootic Hemorrhagic disease (EHD) Diagnosed in Eastern WA Cows
    The Washington Animal Disease Diagnostic Laboratory (WADDL) at Washington State University has detected epizootic hemorrhagic disease virus (EHDV) in cattle located in Eastern WA.  Epizootic hemorrhagic disease typically affects wild deer populations but occasionally crosses over to cattle where most infections are subclinical.  Sporadic disease as seen in these cases in cattle presents as animals off feed with oral erosions and ulcerations, excessive salivation and nasal discharge.
