I'm trying to get a sense of how common this is. In California, for the whole year of 2023, there were 9,280 cases, according to the article. But...<p><i>The majority of people who contract valley fever - some 60 percent - will never know they crossed paths with killer spores, because their immune system is able to rapidly vanquish the fungal intruder.</i><p>Whereas "between 1% and 5%" reach a stage with multiple serious symptoms (which can include death) -- so, between 92 and 460 Californians. But no stats on what subset of those numbers end up as fatalities.<p>Among the whole U.S. population of 331 million people, "approximately" 200 die annually from the disease. (Which I believe comes out to .00006042296 percent).<p>Still, I guess the larger point stands. Climate-induced weather changes could bring numerous unintended side effects, which include increased prevalence of some diseases.
