Abbreviations: CI, confidence interval; OR, odds ratio.

At least 1 mid-gut positive for oocytes in a pool of at least 25 mosquitoes that fed on a single study participant. P values and ORs from univariate logistic regression model with random intercepts for household.

Number of mid-guts positive for oocysts in a pool of at least 25 mosquitoes that fed on a single study participant. Due to overdispersion in oocyst prevalence, CIs are given as basic bootstrapped CIs (1000 repetitions). P values and ORs from univariate beta-binomial regression model with random intercepts for each household.
