Epizootic haemorrhagic disease (EHD) affects:
- cattle
- deer
- other ruminants (animals that chew cud, like goats and sheep)
The disease can cause large outbreaks in susceptible animals. This can result in trade and movement restrictions.
EHD does not affect people or food safety.
Epizootic haemorrhagic disease is a notifiable animal disease. If you suspect it you must report it immediately. Failure to do so is an offence.
In England, call the Defra Rural Services Helpline on 03000 200 301.
In Wales, call 0300 303 8268.
In Scotland, contact your local Field Services Offices.
Current situation
Outbreaks of EHD in cattle have been reported for the first time in southern Europe in November 2022. It is not currently present in the UK.
How to spot EHD
You are only likely to see signs of EHD in severe infections. The main signs are:
- fever
- weakness
- lack of appetite
- more saliva than usual
- difficulty swallowing
- skin rash on the udder
- bleeding (skin and internal tissues)
- swollen red skin near hooves
- swollen lining of the mouth
- mouth ulcers
- difficulty breathing
- sudden death (particularly in deer)
Wild ruminants such as deer may also:
- have a swollen face
- have redness of the eyes and mouth
- have excessive bleeding (in diarrhoea and urine)
- be dehydrated
In some cases there are no obvious clinical signs that an animal is infected.
How EHD is spread
EHD is usually spread when midges that carry it bite susceptible animals and pass on the infection.
EHD could spread to the UK if infected midges are carried by the wind. The risk of this happening depends on:
- whether disease spreads to animals in nearby areas of Europe
- the presence of infected midges in nearby areas of Europe
- weather patterns
EHD could also spread to the UK if infected live animals, or their germinal products, are imported from countries where EHD is circulating.
Whether EHD can be transmitted through germinal products such as semen or embryos, or iatrogenic transmission (for example, contaminated needles) is unknown but cannot be excluded.
Preventing and controlling EHD
There is no commercially available vaccine to protect against EHD.
You can help prevent EHD by practising strict biosecurity on your premises.
If you suspect an animal has EHD or any notifiable disease you must report it to the Animal and Plant Health Agency (APHA) by calling 03000 200 301. Following a report, APHAvets will investigate.
If EHD is confirmed, the outbreak will be controlled in line with the contingency plan for exotic notifiable diseases.

Importing animals to Great Britain
Before importing cattle, deer and other ruminants to Great Britain (England, Scotland and Wales) you should:
- get advice from your vet about the risks and the health status of animals
- check for current issues relating to animal imports
- consider asking the seller to test for EHD
- make sure the animals meet the health and test requirements inthe model health certificate
