Molecular detection of EHV-4 by PCR is the most sensitive, specific, and accurate tool to assess the infectivity of an affected horse. Sample 1 nasal or nasopharyngeal swab (see AAEP guidelines) 5 mL K3 EDTA tube (blood) 20g placental or fetal tissue in a sterile flask Turnaround time 2 to 5 working days What is Herpesvirus Type 4? EHV-4 is a global health risk. Clinical presentation alone is often insufficient for diagnosis as signs overlap with other respiratory diseases. Clinical signs Infections are restricted to respiratory tract epithelium and associated lymph nodes. Abortion in pregnant mares is rare with EHV-4 strains. Establishes latent infection in most horses; viral shedding can reactivate during periods of stress. Transmission Spread via aerosolized secretions from coughing horses. Direct horse-to-horse contact or indirect contact via contaminated objects (fomites). Healthy-appearing horses may still shed the virus through nasal secretions. The environment/air around an infected horse can be contaminated with the virus. Prevention Herd elimination is nearly impossible due to the carrier state; focus on disease prevention. Strategy: Prophylactic immunization and preventive herd management practices. Management: Isolate horses in small closed groups and minimize stress. During outbreaks: Disinfect contaminated areas, isolate affected animals, and implement strict biosecurity protocols.
