Abstract
The presence of parasites in soil remains a major public health problem in developing countries. Classified by the World Health Organization as neglected tropical diseases, infections caused by these organisms are associated with social vulnerability, poverty, and delayed cognitive development, thus representing one of the main working goals of the 2030 Agenda. The objective of the present study was to determine the prevalence of parasites in the recreational sand of public schools and squares in the city of Sinop, in Midwestern Brazil. Sand samples were collected in two phases, one in the dry season and the other in the rainy season. Analyzes were performed according to the methods of Hoffman, Pons and Janer and Rugai modified. All collection sites showed parasitological contamination. The most abundant parasites in both methods were Giardia spp., hookworm larvae, and Balantidium coli. Multiple infestations were detected in several samples. Stray animals or feces were observed in all sandboxes alongside the collection journeys. A statistically significant difference in the prevalence of positive samples was observed during the rainy season compared to the dry season. In view of the results, it is possible to observe the risk associated with the use of such contaminated sites by the potentially exposed population, whether for recreational or sporting purposes. The sensitization of society and government, the improvement of infrastructures, and the adequate treatment and replacement of sand are essential means to address the problems identified.
