Bolivia 239,942 9.9–45.4 23,754–108,933

Chile 45,515 0.4–1.2 182–546
Total 1,541,608 36,567–122,232
No. adults¶

Estimated no. chagasic cardiomyopathies 5,897–29,409

*Infection determined on the basis of seroprevalence data from blood donors.
†Data obtained from the Instituto Nacional de Estadística (5).
‡Data obtained from Schmunis and Cruz (2).
§Calculated by applying seroprevalence data for blood donors in countries endemic for Chagas disease to no. immigrants from each of these countries living in Spain.
¶A correction factor for age was applied (80.2% of immigrants in Spain are adults).
