Nine equine fever cases confirmed

Nine cases of equine infectious anaemia, or swamp fever, have now been confirmed by the Department of Agriculture.

The latest case was reported on Sunday night and test results are expected this morning on a number of suspect cases. Thirteen premises, mainly in Kildare and Meath, have had their movement restricted since the first case was reported on June 15th.

Swamp fever is a persistent viral infection of horses but poses no threat to humans. It is most common in hot weather as it is usually transmitted through blood-sucking insects. It only arrived here in June, despite serious outbreaks in Europe, America and Asia in the past.

Michael Sheridan, deputy chief veterinary officer at the Department of Agriculture, said the outbreak was following the expected pattern. He said on RTÉ Radio yesterday that animals which had been in contact with infected horses were being traced. The first Irish case was thought to be caused by infected equine serum which was being used to treat another equine disease.

About 2,200 animals have now been tested for the virus.

The department has asked horse-owners to be vigilant and to contact their veterinary surgeon if they have any concerns. Symptoms are a flu-like illness, intermittent fever and anaemia.

Horse-owners have been advised to keep animals away from wetlands and wooded areas, where there are large concentrations of horseflies.
