Figure 2. — Exposure model structure. Time is denoted as “T.” State (S) is a combination of behavior (BEH) and compartment (COMP). Competing Hazard model will generate the next time (T) and state (S) until T_n − T₀ > 14 hours. Behavior sequence, defined by Teunis et al.,¹⁵ consists of a sequence of T and a sequence of S. Microbe number on hands (NH) and microbe number ingested (NI) will also be sequences generated by exposure modules selected based on current duration (difference in time) and state.
