[Cost effectiveness study of a control program of congenital Chagas disease in Bolivia]

Abstract

Cost effectiveness analysis of Chagas' vertical transmission control program in Bolivia: Today, Bolivia is the most concerned country in America by Chagas disease: Trypanosoma cruzi infection affects 20% of whole population, around 1800000 inhabitants, and mother-to-child transmission is around 5%, from 1.6 to 9.8%. Direct and indirect costs derived from disease complications and death, from birth to adulthood, add up around US$ 21 millions per year for 2,718 infected new-borns. This cost falls on individual, family and society, when the nation is struggling in a depressed economy. On the other side, an effective control program could detect and treat all cases with an investment of US$ 123 per infected new-born, or US$ 1.2 per new-born in Bolivia. Indirect benefits, apart of suffering relieve and improving of life quality, are related with Chagas vector control program, increasing the demand thanks to increasing risk awareness and also induced demand testing all pregnant women in endemic areas. So the conclusion is that such investment is profitable.
