This study assesses potential associations linked with parasite in symptomatic asymptomatic children Zambézia province, Mozambique. Methods In this prospective cross-sectional study, stool samples epidemiological questionnaires demographics risk were collected from (n = 286) clinical settings 807) 17 schools creches aged 3?14 years. We detected using PCR-based methods. calculated prevalence (adjusted for age, sex, house construction, drinking water, latrine use) odds ratios (ORs) logistic regression, after adjusting district, neighbourhood symptoms. Results Numbers adjusted (95% confidence intervals parentheses) populations Giardia duodenalis 120, 52% (22–82), 339, 42% (25–59); followed Strongyloides stercoralis 52, 14% (9?20), 180, 20% (15–25). Risk G. included untreated river/spring OR 2.91 (1.80–4.70); contact ducks, 14.96 (2.93?76.31); dogs, 1.92 (1.04–3.52); cats, 1.73 (1.16–2.59), a relative diarrhoea, 2.59 (1.54?4.37).
