Modeling Contagiousness of Diarrhea Diseases: A Spatial Probit Model

Every year some two million death including some 1.7 million deaths among children under five years old are caused by diarrhea diseases. Identifying the diseases risk factors becomes crucial in designing an effective intervention for reducing the diseases occurrences. Accordingly, a researcher has to translate the diseases behavior in a mathematical model accurately to obtain good estimates. Nevertheless, we observed that none of the researchers has taken contagiousness into account in a diarrhea prevalence model. In this paper, we propose a spatial probit model to accommodate the contagiousness of diarrhea. Particularly, we propose a format of contiguous matrix used in the model. Although we cannot illustrate the proposed model fully, we apply the model to the data sample of children under five years old in a district in Indonesia. We find out that the occurrence of diarrhea in a child relates to the diarrhea occurrence of the other children in the same area.
