ABSTRACT
Diseases arising from the imbalance between the triad environment, humans, and animals affect individuals' health, as well as the social, and economic well-being of the world's population. Across the globe, health education activities are being conducted to prevent and control zoonoses. To guide future educational interventions, we reviewed scientific articles published in the last five years to characterize and verify the tools: target audience, duration, effectiveness, and gaps and difficulties. Four databases were searched, and 16 articles were selected for the meta-analysis, with 81.3% of the studies being conducted in underdeveloped or developing countries. Of these, 56.3% involved children under 14 years of age, and 62.5% involved activities in elementary and middle schools. The researchers are the professionals who are the most engaged in the activities, and 56.3% of the studies are conducted by veterinarians. Several new teaching tools have been proposed, demonstrating remarkable effectiveness. For systematic reviews to provide a guide for the design of new educational activities, it is necessary to better describe teaching methodologies and evaluation tools, as well as to evaluate in the long term, not only the impact of knowledge on the population but also the incidence of zoonoses.
As doenças decorrentes do desequilíbrio entre a tríade ambiente, humanos e animais afetam a saúde dos indivíduos, bem como o bem-estar social e econômico da população mundial. Em todo o mundo, atividades de educação em saúde estão sendo realizadas para prevenir e controlar zoonoses. Para orientar futuras intervenções educativas, revisamos artigos científicos publicados nos últimos cinco anos para caracterizar e verificar as ferramentas: público-alvo, duração, efetividade, lacunas e dificuldades. Quatro bases de dados foram pesquisadas e 16 artigos foram selecionados para a meta-análise, com 81,3% dos estudos sendo conduzidos em países subdesenvolvidos ou em desenvolvimento. Destes, 56,3% envolviam menores de 14 anos e 62,5% envolviam atividades no ensino fundamental e médio. Os pesquisadores são os profissionais mais engajados nas atividades, sendo que 56,3% dos estudos são conduzidos por veterinários. Várias novas ferramentas de ensino foram propostas, demonstrando notável eficácia. Para que as revisões sistemáticas orientem o desenho de novas ações educativas, é necessário descrever melhor as metodologias de ensino e os instrumentos de avaliação, bem como avaliar a longo prazo não só o impacto do conhecimento na população, mas também a incidência de zoonoses.

En todo el mundo se están realizando actividades de educación sanitaria para prevenir y controlar las zoonosis. Para orientar futuras intervenciones educativas, revisamos artículos científicos publicados en los últimos cinco años para caracterizar y verificar las herramientas: público objetivo, duración, efectividad, vacíos y dificultades. Se realizaron búsquedas en cuatro bases de datos y se seleccionaron 16 artículos para el metanálisis, y el 81,3 % de los estudios se realizaron en países subdesarrollados o en vías de desarrollo. De estos, el 56,3% involucraba a niños menores de 14 años y el 62,5% involucraba actividades en educación primaria y secundaria. Los investigadores son los profesionales más comprometidos con las actividades, siendo el 56,3% de los estudios realizados por veterinarios. Se han propuesto varias herramientas didácticas nuevas que han demostrado una eficacia notable. Para que las revisiones sistemáticas orienten el diseño de nuevas acciones educativas, es necesario describir mejor las metodologías docentes y los instrumentos de evaluación, así como evaluar a largo plazo no solo el impacto del conocimiento en la población, sino también la incidencia de las zoonosis.

Abstract INTRODUCTION: Visceral leishmaniasis (VL) is an important zoonosis in Brazil. Previous identification of parasitized dogs can also help prevent the disease in humans, even in non-endemic areas of the country. The Brazilian Ministry of Health recommends diagnosis in dogs using a DPP® (rapid test) as a screening test and an immunoenzymatic assay (ELISA) as a confirmatory test (DPP®+ELISA), and culling infected dogs as a legal control measure. However, the accuracy of these serological tests has been questioned. METHODS: VL in dogs was investigated in a non-endemic area of the São Paulo state for three consecutive years, and the performances of different diagnostic tests were compared. RESULTS: A total of 331 dog samples were collected in 2015, 373 in 2016, and 347 in 2017. The seroprevalence by DPP®+ELISA was 3.3, 3.2, and 0.3%, respectively, and by indirect immunofluorescence assay (IFA), it was 3.0, 5.6, and 5.5%, respectively. ELISA confirmed 18.4% of DPP® positive samples. The concordance between the IFA and DPP® was 83.9%. The concordance between IFA and DPP®+ELISA was 92.9%. A molecular diagnostic test (PCR) was performed in 63.2% of the seropositive samples, all of which were negative. CONCLUSIONS: In non-endemic areas, diagnostic tests in dogs should be carefully evaluated to avoid false results.
