2007 Australian equine influenza outbreak

2007 outbreak of equine influenza in Australia

The 2007 Australian equine influenza outbreak was a significant event in the history of equine influenza in Australia. It marked the first time the disease was detected in the country, leading to widespread disruption in the horse racing and equine industry.

Background

Equine influenza is a highly contagious respiratory disease affecting horses, donkeys, and mules. It is caused by strains of the influenza A virus, specifically the H3N8 subtype. Prior to 2007, Australia was free of equine influenza, largely due to strict biosecurity measures.

Outbreak

The outbreak was first detected in August 2007 in New South Wales. The initial cases were traced back to horses imported from Japan, which were housed at the Eastern Creek Quarantine Station. The virus quickly spread to other parts of New South Wales and Queensland, affecting thousands of horses.

Spread and Impact

The rapid spread of the virus was facilitated by the movement of horses between properties and events. The outbreak led to the cancellation of major horse racing events, including the prestigious Spring Racing Carnival. The equine industry suffered significant economic losses, estimated to be in the hundreds of millions of dollars.

Response

The Australian government implemented strict movement restrictions and quarantine measures to contain the outbreak. A national standstill on horse movements was declared, and a vaccination program was initiated to control the spread of the virus. The response involved collaboration between federal and state governments, as well as industry stakeholders.

Containment and Eradication

By December 2007, the outbreak was largely contained, and Australia was declared free of equine influenza in March 2008. The successful eradication was attributed to the swift response and effective implementation of biosecurity measures.

Legacy

The 2007 outbreak highlighted the importance of biosecurity in preventing the introduction of exotic diseases. It led to improvements in quarantine protocols and increased awareness of the risks associated with the international movement of horses.
