New Equine Virus test launched
NEV is often misdiagnosed or hidden by other diseases that cause similar symptoms.
Test to prevent misdiagnosis of often fatal disease

The first commercial diagnostic test for New Equine Virus (NEV) has been launched.

First discovered in 2013, NEV is often misdiagnosed or hidden by other diseases that cause similar symptoms, such as anaemia and neurological problems.

It is most often confused with the Swamp Fever virus (EIAV) and Equine Herpesvirus (EHV).

Now, thanks to research by equine biotech firm Equigerminal, vets, laboratories and horse owners will be able to identify this often fatal disease and administer the appropriate treatment.

The test requires a vet to take a blood sample from the horse and send it to the Equigerminal lab. The blood is then analysed and the results are returned to the owner or vet.

When the results are returned, the horse can be given treatment and the spread of the disease can be prevented. Currently, treatment is aimed towards improving the general wellbeing of the horse, monitoring its health and boosting the immune system.

NEV was discovered by Portuguese scientist and veterinary surgeon Isabel Fidalgo Carvalho while completing her PhD in Equine Sciences at the Universities of Oporto and Pittsburgh.

“During my time at University and at Equigerminal, I noticed unusual anaemia and severe neurological signs in horses, which in my PhD I wrongly hypothesized to be attributed to Swamp Fever,” she said. “I then realised, through the samples, that this virus was actually closer to equine HIV – New Equine Virus, or NEV”.

After her discovery, Carvalho launched Equigerminal with fellow scientist Alexandre Vieira Pires.

“We have spent the last five years developing a diagnostic test and a potential cure for NEV.” explains Pires.“We now need to raise awareness of the problem and help vets to diagnose this disease correctly.”

RCVS members invited to question Council candidates

RCVS members have been invited to submit questions to candidates for this year's RCVS Council election.

With 15 candidates standing for three available positions, vets have been invited to submit a question of their choosing before voting starts. These questions will be collated, with each candidate answering one question of their choice.

It is recommended that members read the candidates' biographies and statements before submitting questions. One question per member can be submitted to vetvote26@rcvs.org.uk before Wednesday, 25 February 2026.

The RCVS Council election is due to start in March.

With only two candidates for two positions on the VN Council, there will be no VN Council elections this year. Meghan Conroy RVN and Lauren Hargrave RVN will begin their three year terms at RCVS' AGM in July.
