For dts models, compute
the attack rates, the expected probability of infection
over one time step, is a weighted sum of local and travel exposure.
Usage
# S3 method for class 'dts'
Exposure(t, y, xds_obj)Details
Local attack rates (AR or \(\alpha\)) are a function of local daily entomological inoculation rates (dEIR or \(E\)), and a model for the probability of infection per infectious bite, \(b\) (from \(F_infectivity\), as defined by an \(\cal X\) model). The total attack rates also consider exposure to malaria while traveling, (\(T_\delta\)): $$\alpha = 1-((1-\delta) \; F_\alpha(E, b))(1-\delta\; T_\alpha(b))$$
