The most recent Department of Primary Industries (DPI) figures suggest that, in NSW, there are 835 horses infected with Equine Influenza on 119 confirmed properties. An additional suspect 2900 horses on 319 locations are also in quarantine. Charles Sturt University (CSU) senior lecturer in equine medicine, Dr Sharanne Raidal says most importantly, the NSW Deputy Chief Veterinary Officer reports that every one of these cases has been traced from known contact with affected horses. This means that, to date, the disease has not escaped surveillance measures. Dr Raidal warns that only by containing the virus within a small proportion of the total horse population, and allowing the disease to "burn itself out", will "we succeeded in eradicating EI". Continued careful attention to quarantine restrictions and prompt identification of new cases is required for this to happen. A number of horses with high temperatures, but no known risk of disease, have been tested negative. It is important that all such horses are examined as part of routine, ongoing surveillance for spread of the disease.
