Valley Fever was discovered in 1892 and is endemic to the San Joaquin Valley.
The Washington Post reports:
California and federal public health officials say that valley fever, a potentially lethal but often misdiagnosed disease infecting more and more people across the nation, has been on the rise as a warming climate and drought have kicked up the dust that spreads it…
Long-standing concerns about valley fever were heightened last week when a federal health official ordered the transfer of more than 3,000 exceptionally vulnerable inmates from two San Joaquin Valley prisons where several dozen have died of the disease in recent years. A day later, state officials began investigating an outbreak in February that sickened 28 workers at two solar power plants under construction in San Luis Obispo County.
