[Chagas disease in France: estimated number of infected persons and cardiac diseases in 2009, by risk groups].
An estimation of the number of Trypanosoma cruzi infected individuals and expected number of Chagasic cardiomyopathies in France (excluding French Guyana) was conducted in June, 2009 by InVS. Different risk groups were identified: Latino-Americans (LA) from endemic area (naturalized, legal and illegal migrants, adopted children), children born from LA's mother, French Guyanese living in Metropolitan France, expatriated and travellers from endemic countries. Prevalence rates by country of origin were applied to official data on risk populations obtained from the International Adoption Agency, Tourism Direction and French ministries (Finances, Foreign Affairs and Migrations). Around 157,000 individuals were potentially exposed. It is estimated than 1,464 [895-2,619] are infected by T. cruzi, of which 63 to 555 may evolve towards a chronic cardiomyopathy. This figure is within the range of earlier estimations of InVS and Guerri-Guttenberg. Taking into account illegal immigrants, the expected number of infected individuals in France should increase greatly this estimation.
