Prevention or treatment? The introduction of a new antimalarial drug in Angola

This article estimates the effect of the introduction of an effective treatment on prevention behaviors in the case of malaria. We rely on microeconomic data and build up a difference-in-differences analysis of individuals prevention behaviors following the introduction of Artemisinin Combination Therapies (ACTs) in Angola. We exploit differences in terms of treatment intensity across geographic areas and differences in individuals exposure to the introduction of ACTs. Our results suggest that the increase in access to treatment for malaria in Angola may have had a negative impact on the use of Insecticide Treated Nets even though the two were jointly promoted over the period.
