Equine Infectious Disease Surveillance (EIDS) is generously funded by the UK's Thoroughbred industry and is based at Cambridge University. The EIDS team collaborates with equine industry stakeholders to control and prevent equine infectious disease occurrences in the UK. They oversee numerous surveillance schemes to aid the identification and reporting of specific infectious disease occurrences and provide a disease control advice service for veterinary surgeons. EIDS also collate and share disease information, through platforms such as the International Collating Centre (ICC), EquiFluNet and the Equine Quarterly Disease Surveillance report, which is produced by EIDS in collaboration with BEVA and Defra/APHA.
The Horserace Betting Levy Board (HBLB) funded equine influenza (EI) surveillance scheme provides free of charge PCR testing for suspected cases of equine flu in Great Britain. The laboratory testing is conducted on behalf of EIDS and HBLB by Rossdales Laboratories for samples submitted with an appropriately completed scheme submission form.
This scheme is intended to assist treating vets in confirming if influenza is present on a premises and in particular where there may be financial constraints on pursuing diagnostic testing. Importantly, the scheme is intended to also encourage testing in EI vaccinated horses with clinical respiratory signs, which may be suggestive of failure of vaccine efficacy. A prompt diagnosis helps to ensure successful implementation of control measures for an infected premises, limiting spread of flu and its impacts on the industry and welfare of horses. On confirmation of a positive diagnosis of EI, veterinary epidemiologists at EIDS will be able to assist equine vets with relevant outbreak advice.
This scheme also enables epidemiological and virological information to be obtained which is vital to ensure preventive measures such as vaccination are optimally used in our horse population in Great Britain. Identifying risk factors for outbreaks can assist in the design of premises specific biosecurity measures. Virological analyses determine if current vaccines are likely to maintain levels of protection against the circulating field strains of flu virus. Information obtained through this scheme is shared anonymously with stakeholders, through International Collating Centre (ICC) reports, Tell-Tail text alerts which include a link to the ICC report and on the EquiFluNet website. Anonymised data also contribute to further influenza research studies, which are intended to mitigate future major outbreaks of this highly infectious equine respiratory disease.
Below are resources and forms for use by veterinary practices and laboratories collaborating with our various projects. Please click on the associated link to download the resource/form.
The EIDS Outbreak Information Form is for use by veterinary practices to report details of confirmed cases of equine infectious diseases, following laboratory diagnosis in the UK. This information will then be used as the basis for an anonymised report at the county level issued by the International Collating Centre (ICC), which is our international disease dissemination platform and can be accessed here. On completion of the EIDS Outbreak Information Form, please ensure it is returned to us here.
The HBLB Equine Influenza Surveillance Scheme Form is for use by veterinary practices to submit nasopharyngeal swabs from potential equine influenza cases for complementary laboratory testing, funded by the HBLB. Please note that under this scheme, only the laboratory test costs are covered and this form will need to be completed, printed and submitted with a sample to Rossdales Laboratories, who are partnering the scheme, for it to be eligible.
The Viral Isolate Library Sample Submission Form is for use by diagnostic laboratories to submit samples that they have detected positive for equine viruses (such as EIV, EHV-1, EHV-4, EHV-3, EAV) to the UK Thoroughbred industry-supported Viral Isolate Library, which is now based at Rossdales Laboratories. These sample submissions enable further investigation on viral genomics and strain variation and this form should be completed, printed and submitted with samples.
The Equine Infectious Disease Surveillance (EIDS) team is a small, independent, UK-based group made up of equine veterinary epidemiologists (Dr Richard Newton FRCVS and Fleur Whitlock MRCVS) with support secretariat (Maire O'Brien) and is funded by the equine industry. The team is able to assist with the prevention, diagnosis, management and containment of a wide range of equine infectious diseases and to advise veterinary practices on sampling, vaccination, biosecurity and the most appropriate control of different disease situations. The team can be emailed and somebody from the group will respond promptly.
A recent case illustrates the type of assistance that can be provided. In May 2021, a treating veterinary surgeon was dealing with an outbreak of pyrexia and neurological signs on a livery yard with over 60 horses. Preliminary laboratory diagnostics had confirmed cases to be positive for equine herpes virus-1 (EHV-1). There had already been two neurological cases that had required euthanasia due to the severity of their signs. Discussion with our veterinary epidemiologists from the outset enabled the right control measures to be put in place as quickly as possible, to limit further spread of EHV-1. Horses were designated into small groups and each group was isolated from other groups. Additional diagnostic sampling was conducted to understand the extent of the spread of EHV-1 on the premises and this included nasopharyngeal swabs for EHV-1 PCR and blood samples for EHV-1 serology. The results of this testing were analysed by our team and used to determine the next steps that should be taken on the premises. Strict biosecurity measures were kept in place for two weeks and the treating vet kept in regular contact with our epidemiologists. Clearance testing was then conducted to demonstrate that the virus was no longer circulating on the premises. Through a quick diagnosis by the treating vet and effective implementation of control measures to limit further spread, clearance testing demonstrated that the premises could lift restrictions. Ongoing, a biosecurity plan was implemented to reduce the risk of such outbreaks in the future and our epidemiologists assisted in the specifics of this to ensure they were relevant to the premises set-up and the population of resident horses.

After several years in general mixed practice Richard joined the Animal Health Trust, based near Newmarket, Suffolk, the headquarters of British racing, where he acquired a breadth of experience in the epidemiology, surveillance and control of a range of equine infectious diseases, including influenza, strangles and equine herpesvirus. He was the Director of Epidemiology and Disease Surveillance and Acting Director of Research at the Trust when it closed in July 2020. Richard and his immediate team have been retained by the UK Thoroughbred racing and breeding industry and they continue to provide global disease surveillance and advice on disease prevention strategies and management of outbreaks. More recently he has been working as part of the International Equestrian Federation (FEI) Veterinary Epidemiology Working Group, advising the FEI on outbreak management and return to competition following a large outbreak of EHV-1 neurological disease affecting horses attending showjumping events in Spain and Portugal in February and March 2021.LinkedIn
Fleur qualified from the Royal Veterinary College, London in 2012 and following an internship in Dubai, she worked in clinical equine practice in the UK. In 2017 she joined the Epidemiology and Disease Surveillance team at the Animal Health Trust. Fleur works closely with vets to aid infectious disease diagnosis, control and prevention. She also assists with the running of our surveillance schemes and collation of our numerous surveillance reports. Fleur enjoys promoting equine infectious disease epidemiology and regularly provides lectures and educational material on this topic.
