I examine the dynamics between changes in ecosystems, health, and population, particularly in areas at economic and climate change risk. I evaluate who bears the costs, how are they across populations, and what policies can be implemented or have been more successful.
Type of work: Abstract
This research explores the effect of the recent Venezuelan exodus on malaria outbreaks in the Brazilian Legal Amazon. By exploiting mass migration in 2015 as a quasi-experiment, I find that malaria incidence was 26% in 2017 and that cases of malaria doubled with respect to 2014 for the nearest Brazilian border municipality. Moreover, dose response tests show that incidence among the locals remains almost unchanged.
Findings from this research suggest that places where refugees settle, and their living conditions have implications on malaria incidence. Although malaria is not contagious, healthy refugees are prone to acquiring malaria when occupying endemic places that used to be vacant land. Camps are usually very pathogenic environments, densely populated and restricted of sanitation. Latrines and standing water produce the breeding grounds for mosquito proliferation and overcrowding increases the risk of vector contact. Low endemic places can rapidly become epidemic places. The Amazon region is one of the most biodiverse regions of the world, also hosting highly diverse species of malaria mosquitoes. Likewise, the Amazonas is experiencing rapid ecosystem changes due to climate change and deforestation, leading itself to changes in the ecology of vector-borne diseases. Understanding the dynamics between migration and malaria is thus critical to anticipating changes in the geography of malaria.
