Abstract

With 143,910 laboratory-confirmed cases and 41 malaria-related deaths in 2014, Brazil has launched, in November 2015, the Malaria Elimination Plan, with the short-term goal of interrupting Plasmodium falciparum transmission countrywide over the next 15 years. The focal nature of malaria transmission in Brazil suggests that elimination efforts will require a careful prioritization of a few residual malaria pockets. Here we combine classical epidemiological approaches, to characterize risk factors and intervention targets, with population genetics/genomics analyses of parasites, with the ultimate goal of improving current strategies for malaria control and elimination in Brazil. Our field-based studies in the main endemic area of Brazil (Juruá Valley, close to the border with Peru, which accounts for 20% of all infections in this country), focus on asymptomatic infections with low-level parasitemias that create a large and undetected reservoir of infection.
