Confirmed Detections of Equine Herpevirus Type 1 (EHV-1) in QLD

Veterinarians and horse owners are advised to stay vigilant with biosecurity measures to prevent and manage equine herpesvirus type 1 (EHV-1) following 2 recent detections in horses in the state.  

Biosecurity Queensland has confirmed detections of equine herpesvirus type 1 (EHV-1) in one horse with neurological signs in the Townsville region and up to 3 horses with abortions on a single property in the Toowoomba region.  

Endemic to Australia, EHV-1 is a highly contagious viral disease of horses. It commonly causes mild respiratory disease, occasionally abortion and very rarely, neurological signs. The disease is highly contagious and spreads easily by direct horse-to-horse contact or by contaminated equipment (e.g. feed, water buckets or tack).  

Equine Veterinarians Australia President, Dr Albert Sole Guitart, said “Symptoms may include fever, nasal discharge, coughing, depression, and incoordination. In severe cases, horses may experience difficulty standing, urinating, or defaecating”.  

People are not at risk of EHV-1 infection however, other diseases that are transmissible to people such as Hendra virus could present with similar clinical signs. “If any horse owners suspect their animals may be infected or are presenting symptoms, they are strongly encouraged to isolate their horse and contact their treating veterinarian immediately.” said Dr Sole Guitart. 

Horse owners are advised to review their biosecurity protocols, limit horse movements, and consult their veterinarians about vaccination options. Biosecurity Queensland is coordinating with veterinarians and industry stakeholders to monitor the situation and provide guidance on containment and prevention strategies.  

Australian Veterinary Association President Dr Gemma Chuck said, “Veterinarians are the first responders in these cases and they play a critical role in maintaining Australia’s high standard of biosecurity. Vets work closely with affected communities and authorities to ensure the impact of diseases such as EHV-1 is reduced.  They also play an essential role in prevention strategies and horse owners are encouraged to contact their veterinarian for vaccination advice.” 

Authorities are urging horse owners and equine facility managers to immediately report any suspected cases to Biosecurity Queensland on 13 25 23 or via the Emergency Disease Hotline at 1800 675 888. Prompt isolation of affected animals and strict biosecurity measures are essential to prevent further spread.
