Epidemiology of Chagas Disease in Non-Endemic European Countries

Chagas disease results from infection by the protozoan Trypanosoma cruzi and was presviously described as an endemic disease focused in populations living in poor rural areas of Latin American countries. Currently, migrant populations and some modes of transmission such as blood and organ donation or vertical transmission from infected mothers to their children have caused the spread of this disease beyond its natural geographical boundaries. In Europe, Spain, with over half of these migrants, is undoubtedly the most important recipient, followed by Italy, France and United Kingdom. However, in non-endemic countries there is no universal screening systems and also physicians are often poorly trained in recognizing this disease. So far, few countries are aware of the emergence of this disease and only few European countries have established changes in their health system to address this disease. The National European Health authorities should take part to this model-of-care, adapting in this new epidemiological scenario with screening this pathology in blood donors, organ donations or vertically from mother to child at birth. These mechanisms are the main forms of human infestation in nonendemic countries and are, therefore, the major targets for reduction of spread
