Abstract
Neglected diseases include pathologies that are present in populations with few financial resources. The article deals with leptospirosis, which is a systemic infectious disease with transmission, mainly through contact with rodent urine. The objective was to review aspects of leptospirosis that could characterize it as a neglected disease. For this purpose, an integrative review was carried out by searching for articles in the SciELO and PubMed databases, and collecting secondary information, with data obtained through the SINAN platform. The analysis of the results shows that leptospirosis is a prevalent disease in Brazil and the population most affected by the disease is the one with a low income. The cases of leptospirosis were compared with dengue (a disease considered as neglected) and found that despite the dengue has a higher number of cases, leptospirosis has a higher number of deaths. In short, leptospirosis must be included as a neglected disease, because according to Law 13,930 / 19 the percentage of resources from the Health Research Promotion Program must be applied for neglected disease interventions, so this pathology needs greater visibility to be reduced in the population.
