Coccidioidomycosis is a disease of the American continents. It was first described in Argentina in the late 1800s, and most of what is known today was due to investigations made in the United States in the early 1900s. Currently, all countries in between have described cases of coccidioidomycosis, and most have recognized endemic areas.

The incidence of coccidioidal infections in other endemic areas of North and South America outside of the United States is unknown. The infection risk remains highest in the endemic areas of northern Mexico and Central and South America. However, the incidence over time may not mirror the increase seen in the southwestern United States, because the latter increase has been driven by construction and immigration of uninfected individuals into the area.

The prevalence of coccidioidomycosis in the Americas is as follows [23] : 56% in Mexico, 42% in Guatemala, very low prevalence in Venezuela and Colombia, 26% in Brazil, 44% in Paraguay, and 40% in Argentina. In an endemic area of Brazil, coccidioidomycosis has been linked to hunting of armadillos. [15]
