Abstract

Urban visceral leishmaniasis is an emerging zoonosis in Argentina. In the Americas the disease is produced by Leishmania infantum, with dogs as the primary reservoir and phlebotomine sandflies as the vectors. This article presents the experience acquired by professionals from the National Leishmaniasis Program in Argentina as visceral leishmaniasis has emerged and spread, especially in clinical and laboratory diagnosis, disease treatment, vector biology, reservoir management, and conflicts regarding recommendations for infected dogs. Early detection and treatment, along with decentralized and horizontal strategies, will contribute to the decrease in morbidity and mortality associated with visceral leishmaniasis. Control over the transmission and spread of the disease requires integral environmental management and responsible dog ownership. The interests and discourses put into conflict by visceral leishmaniasis are discussed in the framework of the human-dog relationship, and the search for a consensus-based risk discourse is proposed.
