Abstract
School-aged children (SAC) have a considerable burden of intestinal schistosomiasis in Madagascar yet its burden
in pre-school aged children (PSAC) is currently overlooked. To assess the at-risk status of PSAC, we undertook a pilot
epidemiological survey in June 2019 examining children (n = 89), aged 2–4-years of balanced gender, in six remote
villages in Marolambo District, Madagascar. Diagnosis included use of urine-circulating cathodic antigen (CCA) dipsticks
and coproscopy of stool with duplicate Kato-Katz (K-K) thick smears. Prevalence of intestinal schistosomiasis by
urine-CCA was 67.4% (95% confidence interval [CI]: 56.5–77.2%) and 35.0% (95% CI: 24.7–46.5%) by K-K. The relationship
between faecal eggs per gram (epg) and urine-CCA G-scores (G1 to G10) was assessed by linear regression modelling,
finding for every increment in G-score, epg increased by 20.4 (6.50–34.4, P = 0.006). Observed proportions of
faecal epg intensities were light (78.6%), moderate (17.9%) and heavy (3.6%). Soil-transmitted helminthiasis was noted,
prevalence of ascariasis was 18.8% and trichuriasis was 33.8% (hookworm was not reported). Co-infection of intestinal
schistosomiasis and soil-transmitted helminthiasis occurred in 36.3% of PSAC. These results provide solid evidence
highlighting the overlooked burden of intestinal schistosomiasis in PSAC, and they also offer technical guidance for
better surveillance data for the Madagascan national control programme.
