Input data category	Number of times required	Definition
Case	10	An individual animal infected by a pathogenic agent, with or without clinical signs. (OIE terrestrial code)
Time	8	It's the point in time (usually a date) linked to a specific event or on which a given information is recorded
Population	4	As a very broad definition, the population can be described as any group of units sharing a common defined characteristic (OIE). From a statistical point of view, this can be either the target population (i.e. the population to which it might be possible to extrapolate results from a study) or the source population (i.e. the population from which the study subjects are drawn). It is at source population level that a risk assessor is asked to infer
Population size	6	Total number of units in a population
Population composition	5	Description of the population according to defined characteristics e.g. Sex, age, production type
Exposure	5	Epidemiological term applied to any factor (risk factor) that may be associated with an outcome of interest. If the outcome of interest is occurrence of disease, then exposure is any characteristic (e.g. existence of infected animals, vaccination status, etc.) that may affect the health outcome (diseased/not‐diseased) In relation to a given risk factor, an individual animal has come into contact with, or is predisposed to becoming infected with a pathogen which would result in an increased likelihood of becoming infected
Geographical Location	3	The most detailed information on the positioning of an entity on Earth
Test diagnostic sensitivity	2	The diagnostic sensitivity of the analytical test (according to the OIE Manual)
Test diagnostic specificity	2	The diagnostic specificity of the analytical test (according to the OIE Manual)
Animal movements	1	The list of all movements of an animal since its birth until its death, with details on the establishments in which it is kept
Sampling scheme	1	The underpinning rationale/statistical approach used to perform all relevant steps in a sampling exercise, i.e. definition of the goal, estimation of the sample size, selection of the sampling units, etc.
Species/Breed	1	Genus, species and, when relevant, breed of the concerned animals
Vaccination status	1	The status of the animal in relation to the vaccine intervention
