Projection models calculated for a 2010 University of Texas at Austin study show the predicted progressive spread of one of the main carriers of Leishmania through the United States. The top row represents the study's predictions for 2020, the second row 2050, and the third row 2080. Each row represents two different calculation models. The study attributes the predicted spread to warmer overall temperatures as a result of climate change. Credit: University of Texas at Austin / https://doi.org/10.1371/journal.pntd.0000585
