Lumpy skin disease can cause severe illness in susceptible animals. Outbreaks can cause trade and movement restrictions.
Lumpy skin disease does not affect people or food safety.
It has never been present in Great Britain.
How to spot lumpy skin disease
Signs of lumpy skin disease include:
- drop in milk production
- one or more painful, firm nodules on the skin, nose, mouth or body - as the disease progresses these nodules may crust over or necrose, increasing the risk of secondary infection
- yellowish-grey lesions (skin damage) on the tongue
- swollen and tender udder or testicles
- discharge from the nose and eyes
- more saliva than usual
- bulls becoming sterile and cows having abortions
- swollen lymph nodes, for example on the neck
- death (in rare cases)
Some infected animals may not show any signs of the disease.
How to report lumpy skin disease
Lumpy skin disease is a notifiable animal disease. This means that if you suspect it you must report it immediately. Failure to do so is an offence.

How lumpy skin disease is spread
Lumpy skin disease is spread by biting flies and mosquitoes. They can carry the infection to other animals after feeding on the skin lesions of infected animals.
It can also be spread through infected germinal products (bovine semen, ova and embryos).
