*We built the following factors into the model: other infections (Strongyloides stercoralis, A. lumbricoides, E. histolytica, Cryptosporidium spp., T. trichiura, Giardia duodenalis); camp (1, 2, 3); age (infants and toddlers <2 years of age, children 2–18 years of age, adults >18 years of age); and sex. Associations with Cryptosporidium spp. and G. duodenalis were not significant. We used a generalized linear model that used overdispersion with binomial distribution and logit link, and we performed maximum-likelihood analysis using JMP 12.0.1 (https://www.jmp.com/en_us/home.html). NA, not applicable; NS, not significant.
