Shamonda virus confirmed on two Cork dairy farms

Shamonda virus (SHAV) has been confirmed in three cows on two different dairy farms in Co Cork.

Minister for Agriculture Martin Heydon confirmed that the midge-borne disease has been found in samples tested at a private laboratory.

It is the first time the disease has been detected in Ireland.

Shamonda virus has been detected in cattle, sheep, goats, alpacas and horses in Europe, with cattle most commonly affected.

Signs of the disease include fever, diarrhoea, lethargy and reduced milk production.

“My department’s laboratory services are aware of this result and are engaging with the private laboratory to carry out follow-up investigations,” Minister Heydon said.

“This is the first time this emergent virus has been detected in Ireland.

“SHAV is spread by biting midges and is closely related to Schmallenberg virus.

“My department has been monitoring its spread across Europe since the summer.”

Mild illness

The minister highlighted that the disease is not notifiable in Ireland or the EU and thus there are no ramifications for movement or trade restrictions applicable.

“Thankfully, most infected animals have only a mild illness. The main concern is for pregnant animals, where infection may cause pregnancy loss,” he said.

“There is currently no vaccine or treatment. Farmers and horse owners with concerns should contact their private veterinary practitioner for further advice.”
