In December of 1977, in central California’s San Joaquin Valley, a forceful wind carried a cloud of loose topsoil and mustard-colored dirt into the sky. The plume rose to five thousand feet, blotting out the sun four counties away and spreading dust over an area the size of Maine. Its remnants lingered in the air for another day, creating a murky haze that stung the eyes and noses of those in its path. Over the next several weeks, more than a hundred cases of cocci, or “valley fever,” were reported—including six fatalities. The disease is caused by inhaling microscopic spores of a soil-dwelling fungus. “Digging—building, drilling, tilling, clearing—stirs it up,” Dana Goodyear explained, in 2014. “And dry, hot, windy conditions, a regional feature intensified by climate change, disperse it.” As one specialist told her, “If you breathe and you’re warm-blooded, you can get this.” |
