Step 1
Describe at least two quarantine measures
Answer
In Australia, several quarantine measures are implemented to control avian influenza. Firstly, there are stringent border controls which include inspecting incoming flights and shipments for any signs of the virus. Secondly, there is an enforced biosecurity protocol for poultry farms that involves strict cleanliness standards and monitoring for disease outbreaks.
Step 2
Explain how they assist in protecting Australia
Answer
The border controls play a critical role in preventing the introduction of avian influenza into Australia by catching any infected birds or products before they enter. The biosecurity measures on poultry farms prevent the spread of the virus within domestic populations, effectively reducing the chances of local outbreaks.
Step 3
Make judgements about the effectiveness of the measures
Answer
These quarantine measures are highly effective in protecting Australia from potential outbreaks of avian influenza. The low incidence of the disease in domestic populations demonstrates the success of these strategies. However, vigilance is crucial, as the proximity of outbreaks in Indonesia necessitates constant updates and adaptations to these measures to ensure continued effectiveness.
