A cost-benefit analysis of Chagas disease control in north-western Argentina.
Chagas disease has been controlled in the Department of Anta, Province of Salta, Argentina, through a series of vector control interventions beginning in 1983. Based on data from this programme, together with estimates of the value of benefits accruing to the programme due to avoidance of new cases of Chagas disease, we present an analysis of costs and benefits of the vector control interventions. Under all assumptions, the interventions have been highly profitable from a societal point of view, with an internal rate of return in excess of 60%. The net present value of benefits accruing to the programme is estimated to be above US$7 million.
