Abstract

The purpose of this survey is to assess the prevalence of intestinal parasites in a population of subjects recently immigrated and hosted in the Center for the Foreign Family Health in Reggio Emilia, they are recent immigrants without valid residence permit. 160 faecal samples were collected together with peripheral blood samples of the same subjects enrolled in the study with the random methodology for a period of about 4 months after completion of a cognitive-anamnestic cards. A copro-parassitological standard examination, blood count and platelets count were performed.Among the subjects enrolled and who have joined the project, nearly 50% tested positive for one or more pests in the copro-parasitological exams. The species most represented were the protozoa with prevalence of Blastocystis hominis and Dientamoeba fragilis, in respect of Entamoeba coli and Giardia duodenalis; helminths were rarely observed and Hymenolepis nana, Schistosoma haematobium, and Ascaris lumbricoides were observed.The analysis of cognitive-anamnestic cards showed that about half of the parasitized individuals show no clinical symptoms that could be traced to the infection / infestation of parasitic type.The result of this epidemiological survey shows the need to pay more attention to the immigrants as potential carriers of important parasitic infections.
