Dissemination of information on visceral leishmaniasis from schoolchildren to their families: a sustainable model for controlling the disease

Abstract

A model for the dissemination of information on visceral leishmaniasis from schoolchildren to their families was evaluated in two schools in Caeté, Minas Gerais State, Brazil. Age ranged from 9 to 17 years in the two schools, one receiving the intervention (with 92 students) and the other serving as the control (96 students). All the students attended a class and received a pamphlet on visceral leishmaniasis. The intervention consisted of a homework assignment in which the student discussed the class content and pamphlet with a family member. Knowledge by family members (n = 100) on visceral leishmaniasis was evaluated with a pre and post-intervention questionnaire applied by a health agent, who also completed a form on hygiene around the household as observed during the home visit. A significant improvement was observed in knowledge and hygiene (e.g., sweeping of leaves, fruit, and branches from the yards) among the families that were exposed to the intervention (p < 0.05). The spread of information on visceral leishmaniasis by schoolchildren can contribute to measures for preventing the disease.
