We are  very pleased to inform that the English and Spanish versions of this site are available. We intend to make the contents of LAPPIS accessible to a larger number of researchers, extending the discussions on collective health to other countries. Integrality is understood here as a broad concept, a social action which results from the democratic interaction among subjects in their quotidian health care practices, on different system levels. On this site, readers will be able to consult texts on integrality, seek information about our work and actions which helped change the Brazilian health scenario, and to know the researchers who work at LAPPIS.
