The activities described here form part of an extensive programme in place in the Região Arqueológica de Central, state of Bahia, Brazil. After malacological and socio-environmental surveys in the area, a strategy comprising formal and non-formal education with an emphasis on schistosomiasis prevention was developed, introduced, and evaluated. Interviews were conducted of 142 students and 11 teachers, totalling 11 classes at six primary schools. On the basis of those interviews, four display cases and seven panels were prepared. In addition a table was set up where students could participate directly on the subject, drawing and recognising the factors involved in the schistosomiasis cycle. The exhibition was held at the Museu Arqueológico de Central. The endeavours of this paper underline the importance of health education as well as exhibitions to disease prevention activities.

Rock paintings of mammals have been studied in five of the 243 localities contained within the 270,000 km² Archeological Region of Central, Bahia. From features of external morphology, it was possible to recognize 11 mammals represented in the paintings: for five, to attribute the species; another five, the genera; and, for one, merely the family. This study aims to underline the importance of prehistoric man's contribution, by way of these rock paintings, to our knowledge of the mammals depicted, both taxonomically and in terms of their distribution within the bounds of the Project in the State of Bahia.
