What is a key idea in biosecurity?
Prevention is better then a cure! Struck biosecurity protocol + survience
What is key in managing a quarantine breach??
Pathogen specific plan Regular & appropriate diagnostic testing If in doubt consider and animal or place infectious!! Efficient reporting & recording protocol Mass vaccination (if available)Mass treatment
During a exotic disease outbreak do you want diagnostic tests to be highly specific or sensitive?
Specific
What are the two measurements of disease potential?
R0 Epidemic growth rate
What does Ro provide?
How many new infections a single infectious case causes.Provides insight into disease establishment and persistence.
What does the epidemic growth rate account for?
Time it takes for cases to arise. Higher epidemic growth rate = more cases in a shorter period of time!
What is understanding transmission so important?
Predicts epidemic growth rate Effective control programs
What do we need to know when designing a disease specific plan?
1. Transmission potential 2. Mode of transmission 3. Reservoirs in different species 4. Zoonotic potential???
What timely information is essential during an exotic outbreak?
How many animals are infected? Where are they? Where have they been? Contact with other animals and/or humans? (Fomites)
What are the main consequences of importation of exotic diseases? (3)
Economic Loss of disease free status Animal welfare
What is a notifiable disease?

Main aim of the AUSVET plan
Unifying approaches to disease management!
What are some key points included in AUSVET specific disease plans? (4)
Background about disease Principles of control & eradication Rational for there principles Recommended quarantine and movement controls.
What are Operational Procedure Manuals (OPM's)?
Best practise procedures and technical responses to a disease outbreak.
What are the main sections of an AUSVETPLAN?
1. Diseases Strategy2. Operational Procedure Manuals3. Enterprise manuals 4. Control Centre Management Manuals
What info is provided in OPM? (5)
Decontamination Destruction & disposal of animals Animal welfare issues Valuation and compensation for farmersWild animals responses
What does an AUSVET Control Centre Management Manual do?
1. Defines management structures, adjudicated tasks and outlines information flow systems at national, state and local level. 2. Outlines laboratory handling and laboratories procedures.
Why are Control Centre Management Manuals so important?
Most actors normally are self contained actors there many of the communication lines established do not already exist! = UNIFICATION
What are AUSVET enterprise manuals?
Covers the risk to and risk posed by important enterprises (economic + diseases related)
Are Guidance documents part of the AUSTVET plan?
No
What is the role of guidance documents?
Detail how things should be done but not enforceable!
Who are enterprise manuals designed for?
1. People less familiar with the enterprise involved in the response 2. People within the enterprise seeking guidance on operational procedures related to the outbreak
