Close Certo (Right Closeup) is a project developed by the Brazilian Ministry of Health in partnership with the Hornet app, aimed at gay men. The purpose is using technology to warn about the importance of prevention, diagnosis and treatment of sexually transmitted diseases, especially AIDS. Tutors who already use the application will rely on the Health Ministry's technical support to help spreading information to the app’s more than 1 million users in Brazil. The pilot project will take place during the Rio 2016 Olympic and Paralympic Games.
