<p><span class="fontstyle0">Infectious and Parasitic Diseases are a global public health problem. In the State of Alagoas the presence of many rivers, streams, lakes and lagoons favor the proliferation of mosquitoes. In this work we sought to intervene in the maintenance of the health and environment of a school community contributing to the prevention and combat of vector mosquito breeding sites (Aedes sp., Lutzomya sp. Anopheles sp. and C. quinquefasciatus). The implementation of the extension project was approved by the research ethics committee of cesmac university center under no. 2,080,261. A questionnaire containing 26 specific questions about diseases and their vector mosquitoes was applied. Later, lectures were held on the diseases. We also offered a workshop for the construction of the mosquito net and showed a documentary from Fio Cruz. 42.66% of the students were male and 57.34 %were females, the age group ranged from 14 to 22 years. 97.90% of the garbage generated in their homes is taken to the landfill. Fortunately, 39.86% of participants believe that a clean house avoids mosquito foci and 98.60% know that eliminating standing water is important to fight mosquitoes. During intervention actions, students were interested in learning about the consequences of diseases and ways to prevent mosquito proliferation. The results show that students know the importance of avoiding mosquitoes and also know what to do to prevent the proliferation of vector mosquitoes. Therefore, they can be multipliers of good health and environmental practices.</span> <br /><br /></p>
