“…At this stage of life, children have habits such as playing on the floor, putting their dirty hands into their mouths, eating with unwashed hands and having contact with pets that may carry parasite eggs in their hair, making them important sources of parasite infection 12,13 .…”

SUMMARYThe aim of this study was to determine the occurrence of intestinal parasites in a quilombola community from the northern Espírito Santo, Brazil. Descendants of slaves who arrived in Brazil in the sixteenth century, this population settled in the municipality of São Mateus in 1858. Fresh fecal samples from 82 individuals who agreed to participate in the study were collected between August 2009 and July 2010, and immediately sent to the Clinical Laboratory of the Centro Universitário Norte do Espírito Santo of the Universidade Federal do Espírito Santo for analysis. Out of all the participants, 36 (43.9%) were male and 46 (56.1%) were female, whose ages ranged from six to 85 years. The study of the occurrence of intestinal parasites indicated that 35 individuals (42.7%) were infected with at least one intestinal parasite. Among helminths, the most frequent were hookworms, with a rate of 14.6%. With regard to protozoa, Entamoeba coli, Entamoeba histolytica/Entamoeba dispar and Endolimax nana stood out, with frequencies of 23.2%, 8.5% and 4.9%, respectively. The occurrence of biparasitism was observed in 13 of the 82 subjects, accounting for 15.8%, and no cases of multiple parasitic infections were observed. It was concluded that the reduction of cases of intestinal diseases due to parasites will only be achieved with the improvement of basic sanitation and quality of life of quilombola populations.

“…Differences between boys and girls are reported occasionally, with a higher level of infection for boys than girls 4,29,30 . The prevalence found by several authors is smaller among children from four months to two years, increasing progressively until the 5-6 year-old age range 4,31,32 . The growing levels of prevalence for age observed in this study are probably related to the growth process and infant development (mobility and interaction with the environment) and to the longer time of exposure to environmental conditions.…”

“…The nursery group for 2002, aged four months to two years, was found to present the highest prevalence after preschool, a fact which highlights the particular conditions observed in the daycare center environment. Studies report that children's immunological immaturity before six months of age and their dependence on the care of strangers, among other factors, make them more susceptible to injuries of any kind, while the occurrence of parasitism in children in the first months of life has already been reported 32,33 .…”

OBJECTIVE: To estimate the prevalence and incidence of intestinal parasites in children and staff members of 5 municipal daycare centers in Botucatu/SP. Two cross-sectional studies were carried out in 2002 (N=379) and 2003 (N=397) and a longitudinal observational experiment in which the children from 2002 and 2003 were evaluated for a year. Questionnaires were given to staff members and parents of the children, where the following variables were recorded: socioeconomic status, sanitary habits, home, age, gender and presence of domestic animals. Coproparasitologic tests were carried out in child daycare centers. The enteroparasite prevalence was 76.74% in 2002 and 34% in 2003. The variables associated with presence of enteroparasites in the investigation carried out in 2002 were: location of daycare centers (OR=0.27 CI=0.15-0.47); family salary (OR=4.38 CI=1.91-10.04); gender (OR=0.52 CI=0.32-0.85); child's age group (OR=2.08 CI=1.06-4.08), and presence of pets at home (OR=1.85 CI=1.10-3.11); in 2003, the variables were: daycare centers located in peripheral region (OR=0.49 CI=0.31-0.78), family salary (OR=3.69 CI=2.19-6.24); mother's education (OR=6.19 CI=1.81-21.21); gender (OR=0.58 CI=0.36-0.93), and presence of pets (OR=1.68 CI=1.01-2.79). The cohort had 253 children with an incidence of 23.22%. Data from this study highlighted situations of risk in specific populations (daycare centers), which could be useful for other childcare institutions.

“…Recentemente, Chan et al (1994) detectaram que determinados grupos familiares apresentam uma maior predisposição para a infecção por A. lumbricoides e T. trichiura, estando envolvidos fatores endógenos dos indivíduos e/ou fatores exógenos (ambientais). Entendemos então que a diferença entre os nematóides pode estar relacionada com fatores ambientais, como a maior capacidade de produção de ovos pelas fêmeas de A. lumbricoides e/ou uma maior precocidade de aquisição deste helminto (Costa-Macedo & Rey, 1997).…”

Prevalence of intestinal parasites was investigated in 1381 low-income children under five years of age from March 1990 to October 1991 in the city of Rio de Janeiro, Brazil. Stool tests were run using the Blagg et al. method. Observed prevalence of infection was 54.5%. The most frequent parasites were Giardia lamblia and Ascaris lumbricoides (25.0% of the children). A significant statistical difference (p<0.05) was demonstrated between age and infection according to the species of parasite studied. Infection rates demonstrated the need for control of parasites in these child.
