Illustration of inhomogeneous Poisson process simulation.
Fig 2.
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 Tn - T0 > 14 hours. Modules determined by behavior sequences calculate the microbes on hands (NH) and microbes ingested (NI).
Table 1.
Descriptive statistics of child behavior during structured observations at two timepoints.
Table 2.
Rate of subcategory duration-based behaviors and drinking behavior during the structured observations at two timepoints.
Table 3.
Detection and concentration of E. coli in environmental samples at two timepoints.
Fig 3.
Average contribution (in percentage) of exposure to E. coli over 10,000 simulated child days by source and timepoint.
The color represents the average daily exposure from a specific source.
Fig 4.
Fecal microbe transfer networks averaged over 10,000 simulated child days for children at Timepoint 1, subfigure (a), and Timepoint 2, subfigure (b).
The size of arrows and edges are proportional to the log10 of the average numbers of fecal microbes transferred (for 10,000 simulated child days). The color of nodes represents their role in the network. Red: sources; yellow: vehicles (can be source and sink); green: sinks (remove contamination); purple: ingestion. Food is considered as a vehicle and source, while bathing water is considered as a sink and source.
