Human mobility, garimpos and spatiotemporal malaria transmission in the Yanomami Indigenous Territory: a retrospective observational study.

ABSTRACT:

Background

Past research on human mobility and malaria transmission often used coarse spatial scales, limiting effectiveness for targeted control strategies - especially as transmission becomes more localized with lower incidence. This is seen in Brazil's Yanomami Indigenous Territory (YIT), where illegal gold mining (garimpo) and weakened environmental policies have contributed to malaria resurgence. We used epidemiological surveillance data to identify and distinguish localities of likely infection and residence within and near the YIT. We then constructed Malaria Mobility Networks (MMNs) to analyse spatiotemporal malaria transmission patterns from 2007 to 2023.

Methods

MMN quantified diffusion effects and differentiated between autochthonous and imported malaria ca
