When working with a given population, class, ethnicity, locality; one cannot always act based on a pre-established pattern. The pharmaceutical professional must act by investigating the particularities of a place. This book demonstrates the particularities found in the micro-region of Zona da Mata Mineira, especially Muriaé and Eugenópolis in the years 2009-2012. There is special emphasis on the work: Evaluation of the incidence of parasitosis in an elderly population in a public shelter, in the city of Eugenópolis - MG.
