Comments: A 7–year–old Quarter Horse gelding and an 8–year–old Quarter Horse gelding in Stanislaus County were confirmed positive for Equine Infectious Anemia (EIA). Twenty-five (25) potentially exposed horses on the home premises have been tested for EIA with results pending. The twenty-five (25) potentially exposed horses will remain under quarantine until pending lab results are received and their sixty (60) day retest samples are completed as per CDFA and USDA program requirements. CDFA has been on site with continued monitoring of the situation. Epidemiological tracing is ongoing, but transmission is suspected to be iatrogenic.;
