The source-sink dynamics of Plasmodium vivax may undermine malaria elimination efforts in the Amazon: an epidemiological and population genomic study.

Background: Brazil's progress toward malaria elimination has stalled and 163,000 new cases (more than 80% caused by Plasmodium vivax) were recorded in the Brazilian Amazon in 2023. We hypothesize that human mobility continues to disperse parasites from hotspots to areas with decreasing endemicity.

Methods: We analyzed 5.

Fast and slow aging in Brazil: An analysis of inequalities in population dynamics across social groups.

Formalizing the informal? A perspective on informal waste management in the BRICS through the lens of institutional economics.

The resolution of the problem of ever increasing amounts of solid waste is not yet a priority in many developing countries where informal organization has managed to partially tackle the problem. In this article we explore the interface between formal and informal waste management in the BRICS countries (Brazil, Russia, India, China and South Africa).
