Abstract
Objective: to know the distribution of the Planorbid fauna involved in the transmission of schistosomiasis in the natural water collections of Salvador, identifying possible sources of infection. Method: From 2008 to 2016, the water collections of the city of Salvador were identified and researched. Biomphalaria samples were collected and sent to the malacology laboratory and submitted to the cercaria elimination test. Results: In the year 2008, 156 water collections were identified, of which 71.8% (112/156) had B. glabrata presence. In the period from 2009 to 2016 of the samples collected, 11 they were contaminated by S. mansoni. Conclusions: The identification of the outbreaks raises the discussion about the urbanization and maintenance of schistosomiasis mansoni in Salvador. The data collected delimit the likely sources of infection in the city. The identification of the S. mansoni outbreaks is fundamental to subsidize the actions of surveillance and control of this neglected disease, but of great importance for public health.
