Fungal pneumonia is produced by various endemic or opportunistic fungi. This causes fungal infections, such as histoplasmosis, coccidioidomycosis, and blastomycosis that occur after inhaling spores or conidia or reactivating a latent infection. It has to be noted that fungal pneumonia cases are quite difficult to diagnose.
Fungal pneumonia is prevalent in Mexico and other South American countries, as well as African countries.
