Table 1 Model variables and their anticipated relationship to cholera prevalence.
Model Variables | Measure | Hypothesized Relationship |
|---|---|---|
Period | 1 (1983-1989)/0 (1990-2003) | Negative (due to overall decline in cholera incidence) |
Background Population | Total count per period/1000 | Positive (higher population increases cholera risk) |
Flood Protection Status | 1 (Protected)/0 (Unprotected) | Positive (being flood protected increases risk) |
Distance to River | Euclidean distance (km) | Negative (due to decreased risk of flooding further from river) |
Distance to Hospital | Euclidean distance (km) | Negative (due to distance decay of traveling to hospital) |
Outcome Variable | Â | Â |
Cholera Prevalence | Total count per period | Â |
