Insight into the initial spread of equine influenza in NSW
This video provides insight into the initial spread of equine influenza in NSW and its containment.
The video is a day-by-day chart of infection since the start of the outbreak to the end of October, showing each new infected property as it occurs and the concentration of infections in particular areas across the state.
It is narrated by NSW Chief Veterinary Officer, Ian Roth.
One of the key messages of the video is that the most recent outbreaks of infection have occurred due to the virus being carried on people or equipment rather than on horses - thus proving the importance of personal cleanliness and disinfection in the battle against the disease.

Transcript
A movement lockdown was introduced immediately in NSW on August the 25th, when equine influenza was first diagnosed in Sydney.
Over the next few days the number of properties with infected horses rapidly increased as DPI veterinary investigations revealed new cases throughout the Sydney basin, central coast, northern tablelands and north west NSW.
These infections were mainly due to contact with other infected horses before the virus was detected, on the 25th. People unwittingly carrying the virus and airborne spread over short distances also allowed the virus to spread.
Movement and quarantine restrictions initially kept most new infections close to already infected properties, although a few infections caused by prior horse movements soon appeared much further away in new areas such as Dubbo and Mudgee.
Infection quickly spread though the Dubbo district where large numbers of horses are in close proximity, at Mudgee where the horse population is less concentrated and there was much better adherence to quarantine standards and bio security the spread was much slower.
In early October new infections were confirmed at Barmedman and at Wellington. The distance from other infected properties indicates the virus was transferred on people or equipment to these locations. Strict adherence to mandatory biosecurity precautions would have prevented these new pockets from developing.
The number of new infected properties increased until the 26th of September and has steadily decreased since, vaccination has helped greatly with this process.
By the end of October the declining rate of new infections indicated that the DPI control strategy was slowly containing this highly infectious equine influenza virus.
