As a clinic based in the region, we’re seeing the direct effects of both the Vesicular Stomatitis Virus (VSV) and the ongoing EHV-1 (Equine Herpesvirus) outbreaks. Your paperwork requirements are changing immediately. If you’re shipping, showing, or traveling, please read this carefully.
🚨 𝗘𝗛𝗩-𝟭 𝗧𝗿𝗮𝘃𝗲𝗹 𝗥𝗲𝘀𝘁𝗿𝗶𝗰𝘁𝗶𝗼𝗻𝘀 (𝗖𝗿𝘂𝗰𝗶𝗮𝗹 𝗨𝗽𝗱𝗮𝘁𝗲𝘀):
The Arizona Department of Agriculture has implemented immediate changes to restrict potential EHV-1 spread:
• EECVIs are CANCELLED: All Extended Equine Certificates of Veterinary Inspection (EECVIs/6-month passes) have been cancelled and their use is paused for 30 days. You MUST get a new, single-use CVI.
• 5-Day CVI Window: If you’re importing a horse from a state that has had an EHV-1 detection, your CVI is now only valid for 5 days (not 30).
• Temperature Logs: Twice-daily temp logging (>101.5°F is fever) is strongly recommended for all traveling horses, especially for re-entry into Arizona.
🦠𝗩𝗦𝗩 𝗢𝘂𝘁𝗯𝗿𝗲𝗮𝗸 (𝗩𝗲𝘀𝗶𝗰𝘂𝗹𝗮𝗿 𝗦𝘁𝗼𝗺𝗮𝘁𝗶𝘁𝗶𝘀 𝗩𝗶𝗿𝘂𝘀):
Arizona is an index state for VSV. This virus causes painful blisters (lesions) in the mouth, on the muzzle, udder, sheath, and coronary bands.
• VSV Paperwork: Any horse moving from or through an infected area must have a CVI that is valid for no more than 14 days and includes a specific statement certifying the horse is free of lesions and has not been exposed.
• Biosecurity Focus: Since VSV is spread primarily by biting insects, diligent vector control (fly spray, fly traps, mosquito control) is essential on your farm and at all events.
🌐 𝗪𝗵𝗲𝗿𝗲 𝘁𝗼 𝗚𝗲𝘁 𝘁𝗵𝗲 𝗙𝗮𝗰𝘁𝘀:
Avoid the rumors and stay ahead of rapidly changing quarantine zones. The most accurate data for both EHV-1 and VSV is found on the Equine Disease Communication Center (EDCC) website: https://www.equinediseasecc.org/alerts
If you’re traveling soon, call our office at (480) 962-6660 immediately! We need to generate a new, compliant CVI for you and ensure we include all the specific required statements for EHV-1 and VSV.
