2.4 Collecting Information

2.4.1 Checklist For Gathering Information On History Of A Disease Event

  1. Extent of the problem
    1. How many animals at risk, how many are sick and how many have died?
  2. Case definition
    1. Describe clinical signs, including timing of onset of signs, duration, progression and possible recovery.
    2. How many affected animals recovered and how many died?
  3. Animal characteristics and clustering
    1. Collect detailed information on affected and unaffected animals including counts, age, sex, breed, colour, physiologic status (pregnant or lactating), parity, relative production levels, origin, vaccination status, body condition, treatment history.
    2. When did cases occur (timeline) and could this be related to any recent events (feed, management, environmental changes)?
    3. Where did cases occur (identify cases or affected pens on the loadplan)?
    4. Were there any sick or poor condition animals in the mob when loaded?
  4. Management risk factors
    1. Describe the pens or paddocks where affected and unaffected animals are located.
    2. What are the sources of feed and water?
    3. What disease control and hygiene practices have been used: vaccination, parasite treatments, pest control, bedding, waste disposal?
    4. What is the disease history and production history of the mob?
    5. What is the recent movement history for the mob (where have they come from, when, what other animals might they have contacted)?
    6. Are there any problems in neighbouring animals (adjacent pens, paddocks or properties)?
  5. Environmental risk factors
    1. Describe recent weather patterns.
    2. Describe features of the location (topography, soil type, vegetation, wildlife, other animals, people etc).
    3. Any potential poisons or toxins (pesticides, herbicides, fertilizer, dump sites, industrial contamination, poisonous plants)
