The autonomous Valencian Community (Spain) has experienced intense population growth with economic difficulties or deprivation in basic goods, ranking as the sixth Spanish autonomous region with the highest percentage of a population at risk of poverty or social exclusion. The objective of this work is to assess the level of enteroparasites in a Valencian population that meets certain deprivation conditions. A coproparasitological analysis was carried out in 460 users (children and adult relatives) of the 3 Casa Caridad schools in the province of Valencia. The parasite prevalence reached 31.7%, with a higher frequency of pathogens/potentially pathogenic species (66.4%) than non-pathogenic species (33.5%), although symptoms only appeared in 10.3% of those with pathogens/potentially pathogenic species. Of those parasitized, the presence of pathogens/potentially pathogenic species reached 20.6% in individuals living in crowded conditions and 17.5% in those living with pets. Presenting pathogens/potentially pathogenic species infection increased almost fourfold in those of southern European origin. In family groups, infection occurred among all their members, showing interpersonal parasitic transmission linked to both material deprivation and a lack of health education. Improving epidemiological surveillance, health education, and hygiene/sanitation facilities is essential to reduce or eliminate parasitic transmission among those who suffer from certain deprivation conditions.
