Background: In recent years Europe has experienced a dramatic increase in migration flows. Nevertheless, limited data is available about the occurrence of neglected parasitic diseases among migrant population. The purpose of the present study was to evaluate the prevalence of intestinal and urinary parasites in newly arrived asylum seekers.
Methods: A total of 364 newly arrived migrants hosted at the Asylum Seekers Centre of Castelnuovo di Porto (Italy) were screened during 8 months period for intestinal and urinary parasites. Each enrolled subject was interviewed using a standardized questionnaire, with focus on socio-demographical data and risk factors of parasitic infections.
Results: Stool analysis showed a prevalence of intestinal parasites of 20.6%. The travel route did not affect the prevalence of intestinal parasites (p = 0.096), while a significant negative correlation was found between the length of travel and the prevalence of parasite infection (p = 0.019). No statistically significant correlation between gastrointestinal symptoms and the presence of intestinal parasites was detected.
Conclusion: The prevalence of intestinal parasitosis reported in asylum seekers does not necessarily reflect the prevalence of the parasitosis in the motherland. An anamnestic and syndromic approach may not be sufficient to highlight the problem of intestinal parasitic infestations in a screening setting.
