Inclusion of Deprivation in Endemic-Epidemic Models

Deprivation amplification theory suggests that the health effects of individual deprivation are amplified for people who live in areas with greater levels of deprivation. We postulate that health (represented by norovirus incidence) is influenced and amplified by deprivation (a measure that includes socio-economic factors), and believe that this association has been neglected in surveillance models of infectious diseases. We construct a social epidemiological extension of a known surveillance model to evaluate the inclusion of deprivation in surveillance models using the German Index of Socio-economic Deprivation (GISD) in an endemic-epidemic model. We evaluate model types considered in the literature on the basis of Akaike’s information criterion. Our results suggest that a social epidemiological endemic-epidemic model with the GISD for enterically transmitted infections does not need to also include time-varying contact matrices as transmission weights.
