In multivariable analysis, giardiasis (Coefficient = 0.55; 95% CI = 0.15, 0.95; P‐value = 0.008) and EAEC infection (Coefficient = 0.33; 95% CI = 0.06, 0.61; P‐value = 0.02) were found to be significantly associated with faecal MPO concentrations after adjusting for sex, WAMI score, people sleeping per room, anaemia and ferritin. This evidence concerns the gene MPO and giardiasis.
