Mapping the likelihood of introduction and spread of HPAI Virus H5N1 in Indonesia using multicriteria decision modelling
The spatial distribution of disease risk and its visual presentation through risk maps can assist in the design of targeted animal disease surveillance and control strategies. This approach is particularly useful in situations in which empirical data are not readily available (Clements et al 2006),...

The spatial distribution of disease risk and its visual presentation through risk maps can assist in the design of targeted animal disease surveillance and control strategies. This approach is particularly useful in situations in which empirical data are not readily available (Clements et al 2006), or when data are only available on some aspects of the epidemiology of a multi-factorial disease (Tachiiri et al 2006). In such circumstances data on known risk factors can be used to determine those areas in which a specific disease is most likely to occur using knowledge driven models, such as multicriteria decision modelling (MCDM) (Pfeiffer et al 2008). MCDM is an example of a static knowledge-driven modelling approach that can be used to produce qualitative or quantitative estimates of risk ‘based on existing or hypothesized understanding of the causal relationships leading to disease occurrence’ (Pfeiffer et al., 2008). Knowledge of the risk factors associated with the occurrence of a disease and their interrelationships are used to drive the model.
