A new survey of more than 2,250 UK horse owners has revealed significant gaps in understanding around how Equine Herpes Virus (EHV) is transmitted, despite widespread recognition of the risks associated with equine gatherings and travel.
The survey found that over 25% of respondents were unclear about how EHV spreads, with many unaware that the virus can be transmitted not only through direct horse-to-horse contact, but also via airborne droplets, shared equipment, handlers, or contaminated bedding.
EHV is a highly contagious viral disease that can affect any horse or pony. While some cases result in mild respiratory illness or reduced performance, others can progress to severe, and in some cases fatal, disease. Outbreaks can also lead to prolonged yard closures and significant disruption to training and competition schedules.
Awareness gaps despite high levels of movement
Encouragingly, 98% of respondents recognised that equine gatherings pose a risk for disease transmission, and 75% reported that they regularly leave their home premises with their horse. However, this awareness does not appear to translate into a full understanding of everyday transmission routes.
Up to one in four owners did not realise that EHV can spread through indirect contact, highlighting the importance of routine biosecurity measures, such as not sharing equipment, maintaining good hygiene, and monitoring horses closely after travel or mixing with others.
Vaccination mismatch raises concern
The survey also revealed a striking contrast in vaccination practices. While 95% of respondents reported vaccinating against flu and tetanus, only 17% said they currently vaccinate for EHV, despite 86% believing vaccination can significantly reduce disease spread.
However, the findings suggest that attitudes may be shifting. Among owners not currently vaccinating for EHV:
- 78% said they would consider vaccination now that they better understand the potential impact of the disease
- 93% said they would vaccinate if advised to do so by their vet
These results underline the critical role of veterinary guidance in helping owners make informed decisions about disease prevention.
Call for clearer communication and prevention strategies
Dr Wendy Talbot, National Equine Veterinary Manager at Zoetis, said the findings highlight the need for clearer, more consistent communication around EHV risk and prevention.
She noted that while awareness of EHV exists, there is still confusion around transmission and the role of preventative management strategies, and encouraged horse owners to seek advice from their vet on reducing disease risk.
Why this matters
With horses frequently travelling for training, competition and sales, understanding how EHV spreads is essential for protecting both individual horses and the wider equine community. Improved education around biosecurity, early recognition of symptoms, and evidence-based vaccination decisions could play a key role in reducing future outbreaks.
