Provides estimates for critical epidemiological parameters that characterize the spread of bacterial pathogens in healthcare settings. Parameter estimated: Transmission rate (frequency-dependent or density-dependent mass action), importation probability, clearance rate (loss of colonization per colonized person per unit time), surveillance test sensitivity, surveillance test specificity, effect of covariate on transmission (multiplier in relation to overall transmission rate).
