Identification of enteroparasites in recreation areas of elementary schools in Northern Espírito Santo, Brazil.

Abstract

Since sand is an important child means of contagion by enteroparasites, this study aimed to conduct a parasitological evaluation in recreation areas of elementary schools and early childhood education centers, in São Mateus-ES. Sand samples were collected in seven municipal elementary schools and in a municipal kindergarten and nursery center. For the recovery of helminth eggs and protozoan cysts, flotation and spontaneous sedimentation techniques were used. It was found that 77 % of the analyzed institutions were positive for helminth eggs and larvae. Among the eggs and larvae identified, the main were Ascaris lumbricoides and Toxocara canis. Pearson's chi-square test identified the best results when using the spontaneous sedimentation method. Considering that individuals, especially children living in poor sanitation conditions, are more prone to enteroparasites, studies point to the need of the application of preventive and health education measures for the population enrolled in municipal schools in São Mateus.
