Pools versus Queues: The Variable Dynamics of Stochastic “Steady States”

Fig 1

Schematic representation of a mathematical model of within-hospital transmission of C. difficile, adapted from (4).

Healthcare personnel are considered uncontaminated (US) or contaminated (H), and patients are considered to be low risk and uncolonized (UP), low risk and colonized (CP), high risk and uncolonized (UA), high risk and colonized (CA) or actively infected (D). Solid arrows denote transitions between states, while dashed lines indicate routes of transmission and contamination between patients and healthcare personnel.
