With life becoming increasingly urbanised, society is faced with diseases that used to be characterised as mainly rural, where mosquitoes and other animals are also migrating to urban areas. Dengue, as a re-emerging virus in Brazil, has returned with greater force, where new serotypes have been discovered and Dengue Haemorrhagic Fever has emerged. The aim of this study was to assess the approach to dengue with 5 teachers from 3 public schools in Districts IV, II and VI of Fortaleza, according to the low, medium and high incidence of the disease, respectively. Initially, the schools were visited. Subsequently, the contents of the textbooks used by the schools participating in the research were analysed, followed by the application of a questionnaire with open and structured questions to Science and Biology teachers from the same institutions.
