Prevalence of Schistosoma mansoni, soil-transmitted helminths and intestinal protozoa in orphans and street children in Mwanza city, Northern Tanzania.

Background: Parasitic infections are highly prevalent in low-income environments worldwide. While orphans and street children represent a particularly vulnerable population group, they are often exempt from preventive interventions such as Mass Drug Administration. In part, this could be due to a lack of data showing the burden of disease in this group.
