title: Risk of an equine influenza virus reservoir establishing in wild horses in New South Wales during the Australian epidemic.
abstract: Australia has the world's largest population of wild equids and equine influenza (EI) was confirmed on several properties in New South Wales (NSW) close to uncontrolled areas of land during the 2007 outbreak. Likelihood and risk management assessments were carried out to determine the risk of EI infection of the wild horse populations. The likelihood of spread to the wild horse population was determined to be extremely low, but the likelihood of spread from an established wild horse reservoir back to domestic horses was considered high. The most effective mechanism of control was determined to be prevention of the spread of EI into the wild horse population through a vaccination buffer zone between EI infection foci and known wild horse populations.
