Report of the campaign against schistosomiasis in the State of S. Paulo, Brazil

Abstract

The data about Schistosomiasis in the São Paulo State, Brazil, shows that the disease is now here at an expansive stage. To conclude by this, are the discorvery of new active foci in counties where it had been found before and its recrudescence very year producing new autochthonous case. The detection, at the beginning, of other active foci, it is very suggestive too. This was obtained by collecting naturally infected planorbids at places where no autochthonous cases was announced up to date. As a picture of the Schistosomiasis incidence in the State, some data are presented. From 1951 until 31st July 1970, 4499 autochthonous cases were recorded distributed at 30 counties. During the period were imported from other Brazilian places.
