“…However, sub-Saharan Africa, where 90% cases of malaria and 92% of deaths related to malaria have occurred in 2015, still bears the highest burden of the disease [ 1 ]. Most of these cases remain confined to rural and semi-urban areas [ 2 – 4 ] where helminths are co-prevalent [ 5 – 7 ]. In these areas where malaria significantly overlaps with helminth infections, several studies have reported interactions between the two parasitic infections at both immunological [ 8 – 12 ] and epidemiological [ 13 – 16 ] levels.…”

BackgroundMalaria burden remains high in the sub-Saharan region where helminths are prevalent and where children are often infected with both types of parasites. Although the effect of helminths on malaria infection is evident, the impact of these co-infections is not clearly elucidated yet and the scarce findings are conflicting. In this study, we investigated the effect of schistosomiasis, considering soil-transmitted helminths (STH), on prevalence and incidence of Plasmodium falciparum infection.MethodologyThis longitudinal survey was conducted in school-age children living in two rural communities in the vicinity of Lambaréné, Gabon. Thick blood smear light microscopy, urine filtration and the Kato-Katz technique were performed to detect malaria parasites, S. haematobium eggs and, STH eggs, respectively. P. falciparum carriage was assessed at inclusion, and incidence of malaria and time to the first malaria event were recorded in correlation with Schistosoma carriage status. Stratified multivariate analysis using generalized linear model was used to assess the risk of plasmodium infection considering interaction with STH, and survival analysis to assess time to malaria.Main findingsThe overall prevalence on subject enrolment was 30%, 23% and 9% for S. haematobium, P. falciparum infections and co-infection with both parasites, respectively. Our results showed that schistosomiasis in children tends to increase the risk of plasmodium infection but a combined effect with Trichuris trichiura or hookworm infection clearly increase the risk (aOR = 3.9 [95%CI: 1.7–9.2]). The incidence of malaria over time was 0.51[95%CI: 0.45–0.57] per person-year and was higher in the Schistosoma-infected group compared to the non-infected group (0.61 vs 0.43, p = 0.02), with a significant delay of time-to first-malaria event only in children aged from 6 to 10-years-old infected with Schistosoma haematobium.ConclusionsOur results suggest that STH enhance the risk for P. falciparum infection in schistosomiasis-positive children, and when infected, that schistosomiasis enhances susceptibility to developing malaria in young children but not in older children.

Playful educational intervention with schoolchildren on intestinal parasitosis

et al. 2019

Objective: To analyze the playful educational interventions in the knowledge of schoolchildren about intestinal parasitosis. Method: This is a quasi-experimental, non-randomized study, based on pre- and post-intervention, conducted in a public elementary school in a peripheric neighborhood in the city of Ribeirão Preto (SP). The study population consisted of 101 students enrolled in the 5th and 6th grade. For comparison, we used the generalized version of the McNemar chi-squared test. Results: Of the 101 schoolchildren who participated in the study, 48 (47.5%) were female and 53 (52.5%) were male, aged from 9 to 14 years. Students’ knowledge on intestinal parasitic infections has increased significantly after the playful educational intervention. Conclusion: Playful educational interventions are an excellent didactical resource in the teaching-learning process of schoolchildren.

ResumoIntrodução: As enteroparasitoses vêm ocasionando sérios problemas de saúde pública no mundo, sobretudo nos países em desenvolvimento. Mesmo com a população em geral relatando que tem conhecimento sobre as parasitoses intestinais, estudos apontam que não sabem identificar as verminoses. Objetivo: Elaborar, implementar e avaliar um programa educativo sobre parasitoses intestinais em uma escola pública de Ribeirão Preto -SP. Materiais e Métodos: Estudo quase experimental, não randomizado realizado com 56 alunos do 1º a 4º ano do ensino fundamental. Para avaliar o conhecimento dos alunos antes e após intervenção educativa, foi aplicado um questionário semiestruturado (Pré e Pós -teste). Resultados: Houve mudanças nas respostas dos alunos em relação hábitos de higiene, especialmente nas questões sobre como os vermes se alimentam (p=0,008); o que não fazer para não se contaminar com vermes (p=0,05); qual o formato dos vermes quando é ingerido (p=0,001); quais órgãos os vermes atravessam (p=0,001). Assim, ficou evidente que este tipo de atividade educativa foi eficiente para auxiliar na aprendizagem de alunos do ensino fundamental. Discussão: Após a atividade educativa sem notou um crescimento nos acertos para a maioria das questões, contudo ainda houve dificuldades de compreensão sobre os sintomas, o ciclo e quais organismos são vermes. Conclusões: Espera-se que este trabalho incentive profissionais da saúde e da educação a incluir práticas educativas sobre saúde no contexto escolar.

AbstractIntroduction: Enteroparasitosis has been causing serious problems of public health globally, especially in developing countries. Even with the general population reportedly having knowledge about intestinal parasites, studies indicate that they do not know how to identify the verminoses. Objective: To elaborate, implement, and evaluate an educational program on intestinal parasites in a public school in Ribeirão Preto -SP. Materials and Methods: Quase-experimental, non-randomized study conducted with 56 students from the first to the fourth grades of elementary education. In order to evaluate the students' knowledge before and after the educational intervention, a semi-structured questionnaire was applied (pre-and post-test). Results: Changes were evidenced in the students' responses to hygiene habits, especially in questions about how worms feed (p = 0.008); or what not to do to avoid contamination with worms (p = 0.05); what is the form of the worms when ingested (p = 0.001); which organs the worms enter (p = 0.001). Thus, it was evident that this type of educational activity was efficient to help in the learning by elementary school students. Discussion: After the educational activity, growth was noted in the correct answers for most of the questions, however, difficulties persisted in understanding about the symptoms, the cycle, and which organisms are worms. Conclusions: It is hoped that this work will encourage health and educati...
