As the global COVID-19 pandemic advances, it increasingly impacts those vulnerable populations who already bear a heavy burden of neglected tropical disease. Chagas disease (CD), a neglected parasitic infection, is of particular concern because of its potential to cause cardiac, gastrointestinal, and other complications which could increase susceptibility to COVID-19. The over one million people worldwide with chronic Chagas cardiomyopathy require special consideration because of COVID-19's potential impact on the heart, yet the pandemic also affects treatment provision to people with acute or chronic indeterminate CD.

We analyzed the genetic profile of 563 individuals from 12 geographically targeted human populations from Europe, Asia and Africa using 27 human-specific polymorphic Alu insertions. Phylogenetic analyses indicated a clear correspondence between genetic profiles and historical patterns of gene flow and genetic drift. Sub-Saharan African populations (Benin, Cameroon, Kenya and Rwanda) formed a visibly differentiated cluster, indicating the role of the Sahara desert as a strong natural barrier to gene flow.
