  1. N total = 253. The number of observations are listed for each category with percentage in brackets. Positive refers to all non-negative serology results. #Exact logistic regression was used for analyses with cell counts less than 5. Odds ratios (ORs) are listed for each comparison with 95% confidence intervals (CI) in brackets. Bolded CIs and p-values are statistically significant. *Other parasites included B. hominis D. fragilis.
