A real graveyard curse: Archaeologists susceptible to fungal disease
Valley fever is a respiratory disease that can cause flu-like symptoms, rashes, and (sometimes) chronic lung problems. It's caused by a fungus that lives in dry soil, essentially hibernating for years until it's reinvigorated by moisture. Valley fever is best known for infecting prisoners in the American southwest, but it's also an occupational hazard of archaeologists
... who spend most of their lives sifting through the soils where the fungus lives.
