Histo spread (IMAGE)
Caption
The fungus Histoplasma, which causes lung infections, was concentrated in the Midwest in the 1950s and 60s (top map), but now causes significant disease throughout much of the country (bottom). Researchers at Washington University School of Medicine in St. Louis discovered that the three main kinds of soil fungi that cause lung infections have all expanded their ranges in recent decades. Reliance on outdated maps could be causing delayed or missed diagnoses.
