Forest malaria occurs among economically driven migrants working in the Amazon. However, in the literature, conclusions about the role of forest activities in relation to malaria incidence are conflicting. Rerolle et al. investigated the risk of forest malaria in Lao People's Democratic Republic (PDR) in the context of a nationwide malaria elimination program. High-resolution Landsat remote-sensing imagery of forest cover and malaria incidence data were systematically gathered from four northern and four southern districts of Lao PDR between 2013 and 2016. Deforestation in a 30-kilometer radius around villages was associated with higher malaria incidence within a year, particularly of Plasmodium falciparum malaria, but declined over 3 years. In Lao PDR, unlike the Amazon, it is resident not migrant populations who suffer from forest malaria.
